Add TB encoding to VEROALL, VZEROUPPER, and VCVTPS2PD to allow them to be disassembled. Fixes PR10723.

.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.

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

llvm-svn: 138494

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

Fix decoding of Thumb2 prefetch instructions, which account for all the remaining Thumb2 decoding failures found by randomized testing so far.

Fix two more instances of mis-matched operand names breaking disassembly.  Found by randomized testing.
