[AMDGPU] Add default 1 glc operand to rtn atomics

[rampitec]

Summary

This change adds a real glc operand to the return atomic
instead of just string " glc" in the middle of the asm
string.

Improves asm parser diagnostics.

[rampitec]

Added the same change to MUBUF.

LGTM with a minor issue

Could MTBUF be removed?

Is the _1 variant added here rather than replacing the existing one to support an old syntax, or to support disjoint classes of instructions which need different defaults/validation, or something else? I'm not sure I understand, but renaming the _1 to something more descriptive or adding a comment might help. It also seems like the other isX functions are all checking for something distinct (i.e. there is ImmTyOffset, ImmTyOffset0, and ImmTyOffset1 above), is that not needed here?

[rampitec]

Addressed review comments.

This is MatchClass of the GLC_1 operand, and GLC_1 operand is added the same way as GLC_0 was added, this is the default (and in this case forced) value of the GLC operand. It literally matches GLC_1 operand in the instruction inputs. Added comment.

Yep, at the end MTBUF does not need it as it does not have atomics.
