Ignore register mask operands when lowering instructions to MC.
...
This is similar to implicit register operands. MC doesn't understand
register liveness and call clobbers.

Use TableGen'erated pseudo lowering for ARM.

Hook up the TableGen lowering for simple pseudo instructions for ARM and
use it for a subset of the many pseudos the backend has as proof of concept.
More conversions to come.

Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
...
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

Add support for ELF PLT references for ARM MC asm printing. Adding a

new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).

Add support for floating point immediates to MC instruction printing. ARM

VFP instructions use it for loading some constants, so implement that
handling.
Not thrilled with adding a member to MCOperand, but not sure there's much of
a better option that's not pretty fragile (like putting a double in the
union instead and just assuming that's good enough). Suggestions welcome...
