b66f18486a Constrain both operands on MOVZX32_NOREXrr8. 
This instruction is explicitly encoded without an REX prefix, so both
operands but be *_NOREX.

Also add an assertion to copyPhysReg() that fires when the MOV8rr_NOREX
constraints are not satisfied.

This fixes a miscompilation in 20040709-2 in the gcc test suite.

4164f6bbbf 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.

a4a3a5e3c2 two changes: make the asmmatcher generator ignore ARM pseudos properly, 
and make it a hard error for instructions to not have an asm string.
These instructions should be marked isCodeGenOnly.
