Added a handful of x86-32 instructions that were missing so that llvm-mc would
...
be more complete. These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files. Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added. Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records. More missing instructions will be coming.

ARM instructions that are both predicated and set the condition codes

have been printed with the "S" modifier after the predicate. With ARM's
unified syntax, they are supposed to go in the other order. We fixed this

ARM. Apparently we don't generate these instructions often because no one
noticed until now. Thanks to Bill Wendling for the testcase!

Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on
...
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.
