Target/X86/Printer.cpp: Add sizePtr function, and use it instead of

 " <SIZE> PTR " string when emitting assembly.

Target/X86/X86InstrInfo.def: Tidy up a bit:
 Squashed everything down to 118 chars wide, wrapping lines so that
 comment is at the same point on each line. Rename "NoImpRegs" as
 "NoIR". (most instructions have NoImpRegs twice on a line, so this
 saves 10 columns).

 Also, annotate various instructions with flags for size of memory operand.
  (MemArg16, MemArg32, MemArg64, etc.)

Target/X86/X86InstrInfo.h: Define flags for size of memory operand.
 (MemArg16, MemArg32, MemArg64, etc.)
