[DAGCombiner] fold select-of-constants based on sign-bit test
Examples:
i32 X > -1 ? C1 : -1 --> (X >>s 31) | C1

This is a small generalization of a fold requested in PR43650:
https://bugs.llvm.org/show_bug.cgi?id=43650
The sign-bit of the condition operand can be used as a mask for the true operand:
https://rise4fun.com/Alive/paT
Note that we already handle some of the patterns (isNegative + scalar) because
there's an over-specialized, yet over-reaching fold for that in foldSelectCCToShiftAnd().
It doesn't use any TLI hooks, so I can't easily rip out that code even though we're
duplicating part of it here. This fold is guarded by TLI.convertSelectOfConstantsToMath(),
so it should not cause problems for targets that prefer select over shift.
Also worth noting: I thought we could generalize this further to include the case where
the true operand of the select is not constant, but Alive says that may allow poison to
pass through where it does not in the original select form of the code.

Reapply: [Modules][PCH] Hash input files content
Summary:
When files often get touched during builds, the mtime based validation
leads to different problems in implicit modules builds, even when the
content doesn't actually change:
- Modules only: module invalidation due to out of date files. Usually causing rebuild traffic.
- Modules + PCH: build failures because clang cannot rebuild a module if it comes from building a PCH.
- PCH: build failures because clang cannot rebuild a PCH in case one of the input headers has different mtime.
This patch proposes hashing the content of input files (headers and
module maps), which is performed during serialization time. When looking
at input files for validation, clang only computes the hash in case
there's a mtime mismatch.
I've tested a couple of different hash algorithms availble in LLVM in
face of building modules+pch for `#import <Cocoa/Cocoa.h>`:
- `hash_code`: performace diff within the noise, total module cache increased by 0.07%.
- `SHA1`: 5% slowdown. Haven't done real size measurements, but it'd be BLOCK_ID+20 bytes per input file, instead of BLOCK_ID+8 bytes from `hash_code`.
- `MD5`: 3% slowdown. Like above, but BLOCK_ID+16 bytes per input file.
Given the numbers above, the patch uses `hash_code`. The patch also
improves invalidation error msgs to point out which type of problem the
user is facing: "mtime", "size" or "content".

[DebugInfo] Add a DW_OP_LLVM_entry_value operation
Summary:
Internally in LLVM's metadata we use DW_OP_entry_value operations with
the same semantics as DWARF; that is, its operand specifies the number
of bytes that the entry value covers.
At the time of emitting entry values we don't know the emitted size of
the DWARF expression that the entry value will cover. Currently the size
is hardcoded to 1 in DIExpression, and other values causes the verifier
to fail. As the size is 1, that effectively means that we can only have
valid entry values for registers that can be encoded in one byte, which
are the registers with DWARF numbers 0 to 31 (as they can be encoded as
single-byte DW_OP_reg0..DW_OP_reg31 rather than a multi-byte
DW_OP_regx). It is a bit confusing, but it seems like llvm-dwarfdump
will print an operation "correctly", even if the byte size is less than
that, which may make it seem that we emit correct DWARF for registers
with DWARF numbers > 31. If you instead use readelf for such cases, it
will interpret the number of specified bytes as a DWARF expression. This
seems like a limitation in llvm-dwarfdump.
As suggested in D66746, a way forward would be to add an internal
variant of DW_OP_entry_value, DW_OP_LLVM_entry_value, whose operand
instead specifies the number of operations that the entry value covers,
and we then translate that into the byte size at the time of emission.
In this patch that internal operation is added. This patch keeps the
limitation that a entry value can only be applied to simple register
locations, but it will fix the issue with the size operand being
incorrect for DWARF numbers > 31.

[DebugInfo] Add interface for pre-calculating the size of emitted DWARF
Summary:
DWARF's DW_OP_entry_value operation has two operands; the first is a
ULEB128 operand that specifies the size of the second operand, which is
a DWARF block. This means that we need to be able to pre-calculate and
emit the size of DWARF expressions before emitting them. There is
currently no interface for doing this in DwarfExpression, so this patch
introduces that.
When implementing this I initially thought about running through
DwarfExpression's emission two times; first with a temporary buffer to
emit the expression, in order to being able to calculate the size of
that emitted data. However, DwarfExpression is a quite complex state
machine, so I decided against that, as it seemed like the two runs could
get out of sync, resulting in incorrect size operands. Therefore I have
implemented this in a way that we only have to run DwarfExpression once.
The idea is to emit DWARF to a temporary buffer, for which it is
possible to query the size. The data in the temporary buffer can then be
emitted to DwarfExpression's main output.
In the case of DIEDwarfExpression, a temporary DIE is used. The values
are all allocated using the same BumpPtrAllocator as for all other DIEs,
and the values are then transferred to the real value list. In the case
of DebugLocDwarfExpression, the temporary buffer is implemented using a
BufferByteStreamer which emits to a buffer in the DwarfExpression
object.

[DebugInfo] Remove some users of DBG_VALUEs IsIndirect field
This patch kills off a significant user of the "IsIndirect" field of
DBG_VALUE machine insts. Brought up in in PR41675, IsIndirect is
techncally redundant as it can be expressed by the DIExpression of a
DBG_VALUE inst, and it isn't helpful to have two ways of expressing
things.
Rather than setting IsIndirect, have DBG_VALUE creators add an extra deref
to the insts DIExpression. There should now be no appearences of
IsIndirect=True from isel down to LiveDebugVariables / VirtRegRewriter,
which is ensured by an assertion in LDVImpl::handleDebugValue. This means
we also get to delete the IsIndirect handling in LiveDebugVariables. Tests
can be upgraded by for example swapping the following IsIndirect=True
DBG_VALUE:
DBG_VALUE $somereg, 0, !123, !DIExpression(DW_OP_foo)
With one where the indirection is in the DIExpression, by _appending_
a deref:
DBG_VALUE $somereg, $noreg, !123, !DIExpression(DW_OP_foo, DW_OP_deref)
Which both mean the same thing.

Something to notice is that the architecture is unkonwn for all apks. And that's fine, because run-as would be required to gather this information and that would make this entire functionality massively slow.
There are still several improvements to make here, like displaying actual user names, which I'll try to do in a following diff.
Note: Regarding overall apk debugging support from lldb. I'm planning on having lldb spawn lldb-server by itself with the correct user, so that everything works well. The initial lldb-server used for connecting to the remote platform can be reused for such purpose. Furthermore, eventually lldb could also launch that initial lldb-server on its own.

[Modules][PCH] Hash input files content
Summary:
When files often get touched during builds, the mtime based validation
leads to different problems in implicit modules builds, even when the
content doesn't actually change:
- Modules only: module invalidation due to out of date files. Usually causing rebuild traffic.
- Modules + PCH: build failures because clang cannot rebuild a module if it comes from building a PCH.
- PCH: build failures because clang cannot rebuild a PCH in case one of the input headers has different mtime.
This patch proposes hashing the content of input files (headers and
module maps), which is performed during serialization time. When looking
at input files for validation, clang only computes the hash in case
there's a mtime mismatch.
I've tested a couple of different hash algorithms availble in LLVM in
face of building modules+pch for `#import <Cocoa/Cocoa.h>`:
- `hash_code`: performace diff within the noise, total module cache increased by 0.07%.
- `SHA1`: 5% slowdown. Haven't done real size measurements, but it'd be BLOCK_ID+20 bytes per input file, instead of BLOCK_ID+8 bytes from `hash_code`.
- `MD5`: 3% slowdown. Like above, but BLOCK_ID+16 bytes per input file.
Given the numbers above, the patch uses `hash_code`. The patch also
improves invalidation error msgs to point out which type of problem the
user is facing: "mtime", "size" or "content".

In the new pass manager use PTO.LoopUnrolling to determine when and how

The default before and after this patch is for LoopUnroll to be enabled,
and for it to use a cost model to determine whether to unroll the loop
(`OnlyWhenForced = false`). Before this patch, disabling loop unroll
would not run the LoopUnroll pass. After this patch, the LoopUnroll pass
is being run, but it restricts unrolling to only the loops marked by a
pragma (`OnlyWhenForced = true`).
In addition, this patch disables the UnrollAndJam pass when disabling unrolling.
Testcase is in clang because it's controlling how the loop optimizer
is being set up and there's no other way to trigger the behavior.

[llvm-profdata] Weaken "malformed-ptr-to-counter-array.test" to appease arm bots
There are a number arm bots failing after r374617 landed, and I'm not
sure why. It looks a bit like the error message llvm-profdata is
expected to print to stderr isn't flushed.
Weaken the test in an attempt to appease the arm bots: if this doesn't
work, that means that llvm-profdata is actually *not failing*, and that
will be a clear indication that some logic error is actually happening.
