[lldb/qemu] Add support for pty redirection
Lldb uses a pty to read/write to the standard input and output of the
debugged process. For host processes this would be automatically set up
by Target::FinalizeFileActions. The Qemu platform is in a unique
position of not really being a host platform, but not being remote
either. It reports IsHost() = false, but it is sufficiently host-like
that we can use the usual pty mechanism.
This patch adds the necessary glue code to enable pty redirection. It
includes a small refactor of Target::FinalizeFileActions and
ProcessLaunchInfo::SetUpPtyRedirection to reduce the amount of
boilerplate that would need to be copied.
I will note that qemu is not able to separate output from the emulated
program from the output of the emulator itself, so the two will arrive
intertwined. Normally this should not be a problem since qemu should not
produce any output during regular operation, but some output can slip
through in case of errors. This situation should be pretty obvious (to a
human), and it is the best we can do anyway.
For testing purposes, and inspired by lldb-server tests, I have extended
the mock emulator with the ability "program" the behavior of the
"emulated" program via command-line arguments.

This requires making the LLVM dialect type-compatibility check recursively look
at the element types (arguably, it should have been doing than since the moment
the LLVM dialect type system stopped being closed). In addition, have a more

[analyzer] Ignore flex generated files
Some projects [1,2,3] have flex-generated files besides bison-generated
ones.
Unfortunately, the comment `"/* A lexical scanner generated by flex */"`
generated by the tools is not necessarily at the beginning of the file,
thus we need to quickly skim through the file for this needle string.
Luckily, StringRef can do this operation in an efficient way.
That being said, now the bison comment is not required to be at the very
beginning of the file. This allows us to detect a couple more cases
[4,5,6].
Alternatively, we could say that we only allow whitespace characters
before matching the bison/flex header comment. That would prevent the
(probably) unnecessary string search in the buffer. However, I could not
verify that these tools would actually respect this assumption.
Additionally to this, e.g. the Twin project [1] has other non-whitespace
characters (some preprocessor directives) before the flex-generated
header comment. So the heuristic in the previous paragraph won't work
with that.
Thus, I would advocate the current implementation.
According to my measurement, this patch won't introduce measurable
performance degradation, even though we will do 2 linear scans.
I introduce the ignore-bison-generated-files and
ignore-flex-generated-files to disable skipping these files.
Both of these options are true by default.

Microsoft's floating-point to_chars powered by Ryu and Ryu Printf
Microsoft would like to contribute its implementation of floating-point to_chars to libc++. This uses the impossibly fast Ryu and Ryu Printf algorithms invented by Ulf Adams at Google. Upstream repos: https://github.com/microsoft/STL and https://github.com/ulfjack/ryu .
Licensing notes: MSVC's STL is available under the Apache License v2.0 with LLVM Exception, intentionally chosen to match libc++. We've used Ryu under the Boost Software License.
This patch contains minor changes from Jorg Brown at Google, to adapt the code to libc++. He verified that it works in Google's Linux-based environment, but then I applied more changes on top of his, so any compiler errors are my fault. (I haven't tried to build and test libc++ yet.) Please tell me if we need to do anything else in order to follow https://llvm.org/docs/DeveloperPolicy.html#attribution-of-changes .
Notes:
* libc++'s integer charconv is unchanged (except for a small refactoring). MSVC's integer charconv hasn't been tuned for performance yet, so you're not missing anything.
* Floating-point from_chars isn't part of this patch because Jorg found that MSVC's implementation (derived from our CRT's strtod) was slower than Abseil's. If you're unable to use Abseil or another implementation due to licensing or technical considerations, Microsoft would be delighted if you used MSVC's from_chars (and you can just take it, or ask us to provide a patch like this). Ulf is also working on a novel algorithm for from_chars.
* This assumes that float is IEEE 32-bit, double is IEEE 64-bit, and long double is also IEEE 64-bit.
* I have added MSVC's charconv tests (the whole thing: integer/floating from_chars/to_chars), but haven't adapted them to libcxx's harness at all. (These tests will be available in the microsoft/STL repo soon.)
* Jorg added int128 codepaths. These were originally present in upstream Ryu, and I removed them from microsoft/STL purely for performance reasons (MSVC doesn't support int128; Clang on Windows does, but I found that x64 intrinsics were slightly faster).
* The implementation is split into 3 headers. In MSVC's STL, charconv contains only Microsoft-written code. xcharconv_ryu.h contains code derived from Ryu (with significant modifications and additions). xcharconv_ryu_tables.h contains Ryu's large lookup tables (they were sufficiently large to make editing inconvenient, hence the separate file). The xmeow.h convention is MSVC's for internal headers; you may wish to rename them.
* You should consider separately compiling the lookup tables (see https://github.com/microsoft/STL/issues/172 ) for compiler throughput and reduced object file size.
* See https://github.com/StephanTLavavej/llvm-project/commits/charconv for fine-grained history. (If necessary, I can perform some rebase surgery to show you what Jorg changed relative to the microsoft/STL repo; currently that's all fused into the first commit.)

Reland [DwarfDebug] Move emission of global vars, types and imports to endModule()
This patch proposes to move emission of global variables, types,
imported entities, etc from DwarfDebug::beginModule() to DwarfDebug::endModule().
Effectively, this changes nothing but the order of debug entities which
will be as follows:
* subprograms (including related context, local variables/labels,
local imported entities; related types can be created as a part of
the emission of local entities of an abstract subprogram);
* global variables (including related context and types);
* retained types and enums;
* non-local-scoped imported entities;
* basic types;
* other types left (as a part of local variables attributes emission).
Note that the order of emitted compile units may also be changed as now we emit
units that contain subprograms first and then all other non-empty units.
The motivation behind this change is the following:
(1) DwarfDebug::beginModule() is run at the very beginning of backend's pipeline,
from this time IR can be significantly changed by target-specific passes.
If it happens for debug metadata of global entities, those changes will not
be reflected in the emitted DWARF.
(2) imported subprogram names should refer to an abstract subprogram if it exists,
but it isn't known in DwarfDebug::beginModule() (it's possible to make some
guesses based on location info, but it's not quite reliable);
(3) aforementioned entities if they are scoped within a bracketed block
(subject of D113741) couldn't be emitted in DwarfDebug::beginModule()
(they need parent emitted first). Another problem is if to try to gather
some information about local entities and defer their emission
(till subprogram's processing or DwarfDebug::endModule()) all the gathered
details might be irrelevant / invalid by the time the entities are being
emitted (because of (1)).

[Support] Use final filename for Caching buffer identifier
Mach-O LLD uses the buffer identifier of the memory buffer backing an object
file to generate stabs which are used by `dsymutil` to find the object file for
dSYM generation.
When using thinLTO, these buffers are provided by the cache which initially
saves them to disk as temporary files beginning with "Thin-" but renames them
to persistent files beginning with "llvmcache-" before the buffer is provided
to the cache user.
However, the buffer is created before the file is renamed and is given the temp
file's name as an identifier. This causes the generated stabs to point to
nonexistent files.
This change names the buffer with the eventual persistent filename. I think
this is safe because failing to rename the temp file is a fatal error.
