explicit about which subtarget they refer to, and add AVX versions of
the ones we currently don't. Remove old and now wrong comments!

explicit about which subtarget they refer to, and add AVX versions of
the ones we currently don't. Make the mask check more strict, to be
clear it won't be used to match to 256-bit versions!

Perform more thorough checking of t2IT mask parameters, which fixes all remaining crashers when disassembling the entire 16-bit instruction space.

Hook up 64-bit atomic load/store on x86-32.  I plan to write more efficient implementations eventually.

.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

We'll need to pay attention to them when we start getting more serious about
the details of parsing thumb2 assembly.

llvm-svn: 138500

Fix FiXME in test file. Remove FIXME for SUB (SP minus register) since that
form is Thumb2 only.

Fix the test FIXME and add parsing support for the ADD (SP plus immediate)
and ADD (SP plus register) instruction forms.
