The intent of this patch is to add support of -fp-model=[source|double|extended] to allow
the compiler to use a wider type for intermediate floating point calculations. As a side
effect to that, the value of FLT_EVAL_METHOD is changed according to the pragma
float_control.
Unfortunately some issue was uncovered with this change in preprocessing. See details in
https://reviews.llvm.org/D93769 . We are therefore reverting this patch until we find a way
to reconcile the value of FLT_EVAL_METHOD, the pragma and the -E flow.
This reverts commit 66ddac22e2.

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.

The Intel compiler ICC supports the option "-fp-model=(source|double|extended)"
which causes the compiler to use a wider type for intermediate floating point
calculations. Also supported is a way to embed this effect in the source
program with #pragma float_control(source|double|extended).
This patch extends pragma float_control syntax, and also adds support
for a new floating point option "-ffp-eval-method=(source|double|extended)".
source: intermediate results use source precision
double: intermediate results use double precision
extended: intermediate results use extended precision

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.
Requires two small changes:
1. Don't use llvm::ExceptionHandling in LangOptions. This isn't
even quite the right type since we don't use all of its values.
Tweaks the changes made in:
- https://reviews.llvm.org/D93215
- https://reviews.llvm.org/D93216
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.
No behavior change.

Android has a handful of API levels relevant to developers described
here: https://developer.android.com/studio/build#module-level.
`__ANDROID_API__` is too vague and confuses a lot of people. Introduce
a new macro name that is explicit about which one it represents. Keep
the old name around because code has been using it for a decade.
Added support for the options mabi=vec-extabi and mabi=vec-default which are analogous to qvecnvol and qnovecnvol when using XL on AIX.
The extended Altivec ABI on AIX is enabled using mabi=vec-extabi in clang and vec-extabi in llc.
