This line has a TODO comment, but the answer to it seems to be "no"
given that clang itself uses attributes on @try statements in its tests.
This ProhibitAttributes() statement is also dead code since
ProhibitAttributs() does not handle GNU attributes at the moment but
those are the only attributes valid in objc.

We currently use signed long long instead of ptrdiff_t for offsets
in altivec.h. This has never really presented a problem because
all platforms where we use these are 64-bit. However, now that
we have 32-bit targets, we need to use a meaningful type.
1. Skip the temporary file
2. Test cc1 with -S to verify codegen work well. Add '-target-feature
+m' because the backend requires it to calculate the vscaled size/offset.

This moves the two tests we have for importing Objective-C nodes to their own
file. The motivation is that this means I can add more Objective-C tests without
making the compilation time of ASTImporterTest even longer. Also it seems nice
to separate the Apple-specific stuff from the ASTImporter test.

Add overloads that perform subtraction on v1i128 that take and
produce vector unsigned char to avoid needing to use __int128.
The overloads are suffixed with _u128 and are needed for targets
where __int128 isn't supported (AIX).
The OpenCL C specification v3.0.6 s6.15.12.7.5 mentions:
For atomic_fetch and modify functions with key = or, xor, and, min
and max on atomic type atomic_intptr_t, M is intptr_t, and on
atomic type atomic_uintptr_t, M is uintptr_t.
Remove the atomic_fetch_* overloads from opencl-c.h that mix intptr_t
and uintptr_t in the same declaration.

There is no functional change here (hence no new tests). The only change
is to replace a couple uintptr_t members with llvm::PointerIntPair<> to
clean up the code, making it more readable and less error prone.
This cleanup highlighted that the old code was effectively casting away
const. This is fixed by changing some function signatures.

This reverts commit 933d146f38 and 21b211a8f2
(which mis-identified the issue) but restores i586-linux-gnu which was
removed by `Gnu.cpp: remove obsoleted i386 triple detection from end-of-life distribution versions`.
Looks like i586-linux-gnu was not dead enough (used in a sysroot by Fuchsia build bot based on Debian jessie:)
but i486-linux-gnu should be very dead by now.
ROCm has changed installation path to /opt/rocm-{release}. Add detection

Objective-C apparently allows name conflicts between instance and class
properties, so this is valid code:
```
@protocol DupProp
@property (class, readonly) int prop;
@property (readonly) int prop;
@end
```
The ASTImporter however isn't aware of this and will consider the two properties
as if they are the same property because it just compares their name and types.
This causes that when importing both properties we only end up with one property
(whatever is imported first from what I can see).
Beside generating a different AST this also leads to a bunch of asserts and
crashes as we still correctly import the two different getters for both
properties (the import code for methods does the correct check where it
differentiated between instance and class methods). As one of the setters will
not have its associated ObjCPropertyDecl imported, any call to
`ObjCMethodDecl::findPropertyDecl` will just lead to an assert or crash.

There was only an `Import` function for `QualType` but not for `Type`.
For correct import of some AST nodes where not `QualType` is used
an import of `Type *` is needed. (It is the case with

`-module-dir` is a Flang specific option and should not be visible in
Clang. This patch adds `FlangOnlyOption` flag to its definition. This
way Clang will know that it should reject it and skip it when generating
output for `clang -help`.
The definition of `-module-dir` is moved next to other Flang options.
As `-J` is an alias for `-module-dir`, it has to be moved as well (the
alias cannot be defined before the original option). As `gfortran` mode
is effectively no longer supported (*), `-J` is claimed as Flang only
option.
This is a follow-up of a post-commit review for
https://reviews.llvm.org/D95448.

08196e0b2e exposed LowerExpectIntrinsic's
internal implementation detail in the form of
LikelyBranchWeight/UnlikelyBranchWeight options to the outside.
While this isn't incorrect from the results viewpoint,
this is suboptimal from the layering viewpoint,
and causes confusion - should transforms also use those weights,
or should they use something else, D98898?
So go back to status quo by making LikelyBranchWeight/UnlikelyBranchWeight
internal again, and fixing all the code that used it directly,
which currently is only clang codegen, thankfully,
to emit proper @llvm.expect intrinsics instead.
Upon reviewing D98898 i've come to realization that these are
implementation detail of LowerExpectIntrinsicPass,
and they should not be exposed to outside of it.
This reverts commit ee8b53815d.
With this change, on Debian x86-64 (with a MULTILIB_OSDIRNAMES local patch
../lib64 -> ../lib; this does not matter because /usr/lib64/crt{1,i,n}.o do not exist),
`clang++ --target=aarch64-linux-gnu a.cc -Wl,--dynamic-linker=/usr/aarch64-linux-gnu/lib/ld-linux-aarch64.so.1 -Wl,-rpath,/usr/aarch64-linux-gnu/lib`
built executable can run under qemu-user. Previously this failed with
`/usr/lib/gcc-cross/aarch64-linux-gnu/10/../../../../include/c++/10/iostream:38:10: fatal error: 'bits/c++config.h' file not found`
On Arch Linux, due to the MULTILIB_OSDIRNAMES patch and the existence of
/usr/lib64/crt{1,i,n}.o, clang driver may pick
/usr/lib64/crt{1,i,n}.o and cause a linker error. -B can work around the problem.
`clang++ --target=aarch64-linux-gnu -B /usr/aarch64-linux-gnu/lib a.cc -Wl,--dynamic-linker=/usr/aarch64-linux-gnu/lib/ld-linux-aarch64.so.1 -Wl,-rpath,/usr/aarch64-linux-gnu/lib64:/usr/aarch64-linux-gnu/lib`
With this change, for `#include <ar.h>`, `clang --target=aarch64-linux-gnu`
will read `/usr/lib/gcc/aarch64-linux-gnu/10/../../../../aarch64-linux-gnu/include/ar.h`
(on Debian gcc->gcc-cross)
instead of `/usr/include/ar.h`. Some glibc headers (e.g. gnu/stubs.h) are different across architectures.
