Bill Wendling [Tue, 2 Nov 2010 22:31:46 +0000 (22:31 +0000)]
Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.

make the asm matcher emitter reject instructions that have comments
in their asmstring.  Fix the two x86 "NOREX" instructions that have them.
If these comments are important, the instlowering stuff can print them.
