Jake Egan 3b39fa3e28 [AIX] Define __HOS_AIX__ macro only for AIX target
%%%
This patch defines the macro __HOS_AIX__ when the target is AIX and without any dependency on the host. The macro indicates that the host is AIX. Defining the macro will help minimize porting pain for existing code compiled with xlc/xlC. xlC never shipped cross-compiling support, so the difference is not observable anyway.

This is a follow up to the discussion in https://reviews.llvm.org/D107242.

Sam Clegg d1a96e906c [clang][emscripten] Reduce alignof long double from 16 to 8 bytes
This means `max_align_t` is 8 bytes which also sets the alignment
malloc.  Since this is technically and ABI breaking change we have
limited to just the emscripten OS target.  It is also relatively low
import breakage since it will only effect the alignement of struct that
contai `long double`s (extremerly rare I imagine).

Emscripten's malloc implementation already use 8 byte alignement
(dlmalloc uses and alignement of 2*sizeof(void*) == 8 rather than
checking max_align_t) so will not be effected by this change.  By
bringing the ABI in line with the current malloc code this will fix
several issue we have seen in the wild.

Reduces numbers of files built for clang-format from 575 to 449.

1. Don't use llvm::ExceptionHandling in LangOptions. This isn't

   Tweaks the changes made in:

2. Move section name validation code added (long ago) in commit 30ba67439 out
   of libBasic into Sema and base the check on the triple. This is a bit less
   OOP-y, but completely in line with what we do in many other places in Sema.

While e.g. __sanitizer::internal_lseek is defined in sanitizer_solaris.cc, g++ 9
predefines _FILE_OFFSET_BITS=64 while clang++ currently does not.

This patch resolves this inconsistency by following the gcc lead, which allows
make check-all to finish successfully.

There's one caveat: gcc defines _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE for C++ only, while clang has long been doing it for
all languages.  I'd like to keep it this way because those macros do is to make
declarations of fseek/ftello (_LARGEFILE_SOURCE) resp. the 64-bit versions
of largefile functions (*64 with _LARGEFILE64_SOURCE) visible additionally.
However, _FILE_OFFSET_BITS=64 changes all affected functions to be largefile-aware.
I'd like to restrict this to C++, just like gcc does.

To avoid a similar inconsistence with host compilers that don't predefine _FILE_OFFSET_BITS=64
(e.g. clang < 9, gcc < 9), this needs a compantion patch https://reviews.llvm.org/D64483.

    File /vol/llvm/src/clang/local/test/Sema/wchar.c Line 22: array initializer must be an initializer list

It turns out the definition is wrong, as can be seen in GCC's gcc/config/sol2.h:

  /* wchar_t is called differently in <wchar.h> for 32 and 64-bit
     compilations.  This is called for by SCD 2.4.1, p. 6-83, Figure 6-65
     (32-bit) and p. 6P-10, Figure 6.38 (64-bit).  */
  
  #undef WCHAR_TYPE
  #define WCHAR_TYPE (TARGET_64BIT ? "int" : "long int")

The following patch implements this, and at the same time corrects the wint_t
definition which is the same:

  /* Same for wint_t.  See SCD 2.4.1, p. 6-83, Figure 6-66 (32-bit).  There's
     no corresponding 64-bit definition, but this is what Solaris 8
     <iso/wchar_iso.h> uses.  */
  
  #undef WINT_TYPE
  #define WINT_TYPE (TARGET_64BIT ? "int" : "long int")

Clang :: Preprocessor/wchar_t.c and Clang :: Sema/format-strings.c need to
be adjusted to account for that.

Tested on i386-pc-solaris2.11, x86_64-pc-solaris2.11, and x86_64-pc-linux-gnu.
