When asm parser detects an error, it attempts to show the location of an offending operand. Hardcoded literals like those used by `FMAAK/FMAMK` should be ignored, because they are part of the instruction and cannot be changed. This is how it currently works.

GFX11 VOPD is a special case because an instruction may have two hardcoded literals. And if they are different, the parser should show the location of a hardcoded literal.

This change is required for VOPD validation which is WIP.
