[clang-format] improve distinction of K&R function definitions vs attributes
After
https://github.com/llvm/llvm-project/commit/
9da70ab3d43c79116f80fc06aa7cf517374ce42c
we saw a few regressions around trailing attribute definitions and in
typedefs (examples in the added test cases). There's some tension
distinguishing K&R definitions from attributes at the parser level,
where we have to decide if we need to put the type of the K&R definition
on a new unwrapped line before we have access to the rest of the line,
so we're scanning backwards and looking for a pattern like f(a, b). But
this type of pattern could also be an attribute macro, or the whole
declaration could be a typedef itself. I updated the code to check for a
typedef at the beginning of the line and to not consider raw identifiers
as possible first K&R declaration (but treated as an attribute macro
instead). This is not 100% correct heuristic, but I think it should be
reasonably good in practice, where we'll:
* likely be in some very C-ish code when using K&R style (e.g., stuff
that uses `struct name a;` instead of `name a;`
* likely be in some very C++-ish code when using attributes
* unlikely mix up the two in the same declaration.
Ideally, we should only decide to add the unwrapped line before the K&R
declaration after we've scanned the rest of the line an noticed the
variable declarations and the semicolon, but the way the parser is
organized I don't see a good way to do this in the current parser, which
only has good context for the previously visited tokens. I also tried
not emitting an unwrapped line there and trying to resolve the situation
later in the token annotator and the continuation indenter, and that
approach seems promising, but I couldn't make it to work without
messing up a bunch of other cases in unit tests.

I saw in an extreme case, there are thousands of samples whose context stack depth is >= 100. The memory consumption can be greater than 100GB.
As here the context is used for inlining, we can assume we won't have so many of inlinees keeping inlined at the same root function, so this change tried to cap the context stack and merge the samples for peak memory reduction and this is done after recursion compression.
The default value is -1 meaning no depth limit, in the future we can tune to a smaller one.

[OpenMP]Fix PR50336: Remove temporary files in the offload bundler tool
Temporary files created by the offloading device toolchain are not removed
after compilation when using a two-step compilation. The offload-bundler uses a
different filename for the device binary than the `.o` file present in the
Job's input list. This is not listed as a temporary file so it is never
removed. This patch explicitly adds the device binary as a temporary file to
consume it. This fixes PR50336.

[ELF] Don't emit SHF_GNU_RETAIN on Solaris
The introduction of `SHF_GNU_RETAIN` has caused massive problems on Solaris.
Initially, as reported in Bug 49437, it caused dozens of testsuite failures
on both sparc and x86. The objects were marked as `ELFOSABI_NONE`, but
`SHF_GNU_RETAIN` is a GNU extension. In the native Solaris ABI, that flag
(in the range for OS-specific values) is `SHF_SUNW_ABSENT` with a
completely different semantics, which confuses Solaris `ld` very much.
Later, the objects became (correctly) marked `ELFOSABI_GNU`, which Solaris
`ld` doesn't support, causing it to SEGV and break the build. The linker
is currently being hardened to not accept non-native OS ABIs to avoid this.
The need for linker support is already documented in
`clang/include/clang/Basic/AttrDocs.td`, but not currently checked.
This patch avoids all this by not emitting `SHF_GNU_RETAIN` on Solaris at all.
Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11`, and
`x86_64-pc-linux-gnu`.

[InstrProfiling] Generate runtime hook for Fuchsia
When none of the translation units in the binary have been instrumented
we shouldn't need to link the profile runtime. However, because we pass
-u__llvm_profile_runtime on Linux and Fuchsia, the runtime would still
be pulled in and incur some overhead. On Fuchsia which uses runtime
counter relocation, it also means that we cannot reference the bias
variable unconditionally.
This change modifies the InstrProfiling pass to pull in the profile
runtime only when needed by declaring the __llvm_profile_runtime symbol
in the translation unit only when needed. For now we restrict this only
for Fuchsia, but this can be later expanded to other platforms. This
approach was already used prior to
9a041a75221ca, but we changed it
to always generate the __llvm_profile_runtime due to a TAPI limitation,
but that limitation may no longer apply, and it certainly doesn't apply
on platforms like Fuchsia.
