[clangd] Ignore semicolons, whitespace, and comments in SelectionTree.
Summary:
Whitespace and comments are a clear bugfix: selecting some
comments/space near a statement doesn't mean you're selecting the
surrounding block.
Semicolons are less obvious, but for similar reasons: these tokens
aren't actually claimed by any AST node (usually), so an AST-based model
like SelectionTree shouldn't take them into account.
Callers may still sometimes care about semis of course:
- when the selection is an expr with a non-expr parent, selection of
the semicolon indicates intent to select the statement.
- when a statement with a trailing semi is selected, we need to know
its range to ensure it can be removed.
SelectionTree may or may not play a role here, but these are separate questions
from its core function of describing which AST nodes were selected.
The mechanism here is the TokenBuffer from syntax-trees. We use it in a
fairly low-level way (just to get boundaries of raw spelled tokens). The
actual mapping of AST nodes to coordinates continues to use the (fairly
mature) SourceLocation based logic. TokenBuffer/Syntax trees
don't currently offer an alternative to getFileRange(), I think.

[InstCombine] canonicalize fneg before fmul/fdiv
Reverse the canonicalization of fneg relative to fmul/fdiv. That makes it
easier to implement the transforms (and possibly other fneg transforms) in
1 place because we can always start the pattern match from fneg (either the
legacy binop or the new unop).
There's a secondary practical benefit seen in PR21914 and PR42681:
https://bugs.llvm.org/show_bug.cgi?id=21914
https://bugs.llvm.org/show_bug.cgi?id=42681
...hoisting fneg rather than sinking seems to play nicer with LICM in IR
(although this change may expose analysis holes in the other direction).
1. The instcombine test changes show the expected neutral IR diffs from
reversing the order.
2. The reassociation tests show that we were missing an optimization
opportunity to fold away fneg-of-fneg. My reading of IEEE-754 says
that all of these transforms are allowed (regardless of binop/unop
fneg version) because:
"For all other operations [besides copy/abs/negate/copysign], this
standard does not specify the sign bit of a NaN result."
In all of these transforms, we always have some other binop
(fadd/fsub/fmul/fdiv), so we are free to flip the sign bit of a
potential intermediate NaN operand.
(If that interpretation is wrong, then we must already have a bug in
the existing transforms?)
3. The clang tests shouldn't exist as-is, but that's effectively a
revert of rL367149 (the test broke with an extension of the
pre-existing fneg canonicalization in rL367146).

[Sanitizer][ASAN][MSAN] Fix infinite recursion on FreeBSD
Summary:
MSAN was broken on FreeBSD by https://reviews.llvm.org/D55703: after this
change accesses to the key variable call __tls_get_addr, which is
intercepted. The interceptor then calls GetCurrentThread which calls
MsanTSDGet which again calls __tls_get_addr, etc...
Using the default implementation in the SANITIZER_FREEBSD case fixes MSAN
for me.
I then applied the same change to ASAN (introduced in https://reviews.llvm.org/D55596)
but that did not work yet. In the ASAN case, we get infinite recursion
again during initialization, this time because calling pthread_key_create() early on
results in infinite recursion. pthread_key_create() calls sysctlbyname()
which is intercepted but COMMON_INTERCEPTOR_NOTHING_IS_INITIALIZED returns
true, so the interceptor calls internal_sysctlbyname() which then ends up
calling the interceptor again. I fixed this issue by using dlsym() to get
the libc version of sysctlbyname() instead.

[AARCH64] Switch relocations R_AARCH64_TLS_TPREL64 and R_AARCH64_DTPMOD64
The ELF for the Arm 64-bit Architecture document originally specified
R_AARCH64_TLS_DTPREL64 = 0x404
R_AARCH64_TLS_DTPMOD64 = 0x405
LLVM correctly followed the document. Unfortunately in binutils these
two codes were reversed:
R_AARCH64_TLS_DTPMOD64 = 0x404
R_AARCH64_TLS_DTPREL64 = 0x405
Given that binaries had shipped this change has become the defacto standard
interpretation of these relocation codes for any toolchain that wanted to
remain compatible with GNU.
To recognize this the latest version of the ABI document has renamed
the relocations to R_AARCH64_TLS_IMPDEF1 and R_AARCH64_TLS_IMPDEF2
permitting a toolchain to choose between the two relocation types, and
recommending that toolchains follow the GNU interpretation for maximum
compatibility.
Given that upstream llvm has never implemented the standard TLS model for
AArch64 so we have no binary legacy, synchronize with GCC so that we don't
create incompatible objects in the future. So far the only visible change
is in llvm-readobj as it can decode these relocations. Tthis change will

[DivRemPairs] Recommit: Handling for expanded-form rem - recomposition (PR42673)
Summary:
While `-div-rem-pairs` pass can decompose rem in div+rem pair when div-rem pair
is unsupported by target, nothing performs the opposite fold.
We can't do that in InstCombine or DAGCombine since neither of those has access to TTI.
So it makes most sense to teach `-div-rem-pairs` about it.
If we matched rem in expanded form, we know we will be able to place div-rem pair
next to each other so we won't regress the situation.
Also, we shouldn't decompose rem if we matched already-decomposed form.
This is surprisingly straight-forward otherwise.
The original patch was committed in rL367288 but was reverted in rL367289
because it exposed pre-existing RAUW issues in internal data structures
of the pass; those now have been addressed in a previous patch.

Fix issues with inferior stdout coming out of order
Summary:
We've had a bug where two pieces of code, executing on two threads were
attempting to write inferior output simultaneously. The first one was in
Debugger::HandleProcessEvent, which handled the cases where stdout was
coming while the process was running. The second was in
CommandInterpreter::IOHandlerInputComplete, which was ensuring that any
output is printed before the command which caused process to run
terminates.
Both of these things make sense, but the fact they were implemented as
two independent functions without any synchronization meant that race
conditions could occur (e.g. both threads call process->GetSTDOUT, get
two chunks of data, but then end up calling stream->Write in opposite
order). This was most apparent in situations where a process quickly
writes a bunch of output and then exits (as all our register tests do).
This patch adds a mutex to ensure that stdout forwarding happens
atomically. It also refactors a code somewhat in order to reduce code
duplication.

[DivRemPairs] Avoid RAUW pitfalls (PR42823)
Summary:
`DivRemPairs` internally creates two maps:
* {sign, divident, divisor} -> div instruction
* {sign, divident, divisor} -> rem instruction
Then it iterates over rem map, and looks if there is an entry
in div map with the same key. Then depending on some internal logic
it may RAUW rem instruction with something else.
But if that rem instruction is an input to other div/rem,
then it was used as a key in these maps, so the old value (used in key)
is now dandling, because RAUW didn't update those maps.
And we can't even RAUW map keys in general, there's `ValueMap`,
but we don't have a single `Value` as key...
The bug was discovered via D65298, and the test there exists.
Now, i'm not sure how to expose this issue in trunk.
The bug is clearly there if i change the map keys to be `AssertingVH`/`PoisoningVH`,
but i guess this didn't miscompiled anything thus far?
I really don't think this is benin without that patch.
The fix is actually rather straight-forward - instead of trying to somehow
shoe-horn `ValueMap` here (doesn't fit, key isn't just `Value`), or writing a new
`ValueMap` with key being a struct of `Value`s, we can just have an intermediate
data structure - a vector, each entry containing matching `Div, Rem` pair,
and pre-filling it before doing any modifications.
This way we won't need to query map after doing RAUW, so no bug is possible.

Add llvm-style RTTI to ObjectFile hierarchy
Summary:
On the heels of D62934, this patch uses the same approach to introduce
llvm RTTI support to the ObjectFile hierarchy. It also replaces the
existing uses of GetPluginName doing run-time type checks with
llvm::dyn_cast and friends.
This formally introduces new dependencies from some other plugins to
ObjectFile plugins. However, I believe this is fine because:
- these dependencies were already kind of there, and the only reason
we could get away with not modeling them explicitly was because the
code was relying on magically knowing what will GetPluginName() return
for a particular kind of object files.
- the dependencies themselves are logical (it makes sense for
SymbolVendorELF to depend on ObjectFileELF), or at least don't
actively get in the way (the JitLoaderGDB->MachO thing).
- they don't introduce any new dependency loops as ObjectFile plugins
don't depend on any other plugins

Summary:
This patch fixes a bug in the following instructions that should have been

* EORBT/EORTB
* TBX
* Narrowing top instructions
* FP convert precision instructions
These changes are non-functional from the assembler/diassembler point-of-view

[Fix] Customize warnings for missing built-in types
If we detect a built-in declaration for which we cannot derive a type
matching the pattern in the Builtins.def file, we currently emit a
warning that the respective header is needed. However, this is not
necessarily the behavior we want as it has no connection to the location
of the declaration (which can actually be in the header in question).
Instead, this warning is generated
- if we could not build the type for the pattern on file (for some
reason). Here we should make the reason explicit. The actual problem
is otherwise circumvented as the warning is misleading, see [0] for
an example.
- if we could not build the type for the pattern because we do not
have a type on record, possible since D55483, we should not emit any
warning. See [1] for a legitimate problem.
This patch address both cases. For the "setjmp" family a new warning is
introduced and for built-ins without type on record, so far
"pthread_create", we do not emit the warning anymore.

2) Standalone mode: the metadata and the remark entries are in the same
file.
The format contains:
* a meta block: container version, container type, string table,
external file path, remark version
* a remark block: type, remark name, pass name, function name, debug
file, debug line, debug column, hotness, arguments (key, value, debug
file, debug line, debug column)
A string table is required for this format, which will be dumped in the
