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 0d35df1cfe handle the upper16/lower16 target operand flags on symbol references for MC 
instruction lowering.

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...

Jim Grosbach cf98cbaef1 Don't ignore the CPSR implicit def when lowering a MachineInstruction to an MCInst.

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.
