Add MC support for dlc in gfx11 MUBUF atomic instructions.
Improve assembler diagnostics: report error when dlc is used in
gfx10 MUBUF atomic instruction; dlc is ignored in this case.
Matches encoding implementation for gfx10 MUBUF atomics (dlc bit is
set to 0) and disassembler behavior (errors out if dlc is set to 1).
