This adds the required target feature names to x86 builtins that need
particular features. Most have exactly one ("avx", "aes", etc), but some
of the avx512 features have multiple requirements, eg "avx512vl,avx512bw".

This patch fixes bug 23800 ( https://llvm.org/bugs/show_bug.cgi?id=23800#c2 ). There existed a case where the index operand from extractelement was directly used to create a shufflevector mask. Since the index can be of any integral type but the mask must only contain 32 bit integers a 64 bit index operand led to an assertion error later on.

Update testcases after LLVM change r243774.

Most of these had no need to check `tag:` field, but did so as a way of
getting to the `name:` field.  In a few cases I've converted the `tag:`

It doesn't make any sense to enable -gmlt with -gsplit-dwarf, since
-gmlt is designed for on-line symbolication (and -gsplit-dwarf normally
emits all the -gmlt data into the .o anyway - so there's nothing to
split out except redundant/duplicate info).

With this change they override each other, -gmlt -gsplit-dwarf is the
same as -gsplit-dwarf and -gsplit-dwarf -gmlt is the same as -gmlt.

Summary:
Currently, if the argument to _Pragma is not a parenthesised string
literal, the bad token will be consumed, as well as the ')', if present.
If additional bad tokens are passed to the _Pragma, this results in
extra error messages which may distract from the true problem.

The proposed patch causes all tokens to be consumed until the closing
')' or a new line, whichever is reached first.

In llvm commit r243581, a reverse range adapter was added which allows
us to change code such as

  for (auto I = Fields.rbegin(), E = Fields.rend(); I != E; ++I) {

in to

  for (const FieldDecl *I : llvm::reverse(Fields))

This commit changes a few of the places in clang which are eligible to use
this new adapter.

These tests were creating a modules.idx file in my clang checkout, not

All the other tests in this directory use -fmodules-cache-path=%t so
updated these to match.

Copying the already existing code for x86 to ARM to set the correct CPU
features when using -mcpu=native. We can already detect the CPU name
but we were not setting the correct feature bits.

Moving fpu/hwdiv down to make sure they override whatever we set the
default to be.

No tests because this is native detection, and not all ARM-enabled builds
will hapen at a specific CPU, or even ARM. I have tested locally and it
works as expected.

Fixes PR12794.
