Evan Cheng a20cde31e7 Sink ARMMCExpr and ARMAddressingModes into MC layer. First step to separate ARM MC code from target.

Jim Grosbach 95dee40343 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.

Evan Cheng 965b3c7323 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.

Chris Lattner c5afd12557 even more simplifications. ARM MCInstLowering is now just
a single function instead of a class.  It doesn't need the
complexity that X86 does.

Jim Grosbach 85dcd3d0f4 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)).

Jim Grosbach ee1934a2da Make sure to promote single precision floats to double before extracting them
from the APFloat.

Jim Grosbach 298d0fd1c8 store MC FP immediates as a double instead of as an APFloat, thus avoiding an
unnecessary dtor for MCOperand.

Jim Grosbach 7bbf3fd0d6 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...

Chris Lattner b792b463af sink the arm implementations of ASmPrinter and MCInstLower
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.
