[AMDGPU] Reduce repetition in SMEM instruction definitions

[foad]

Summary

This tries to remove all cases where we repeat the instruction name as
both an identifier (the tablegen name) and as a string (the assembler/
disassembler name). It uses tablegen's new !tolower operator.

@dp @kosarev what do you think? Is this going too far? If not we could apply the same technique to other *Instructions.td files.

[piotr]

LGTM - looks cleaner than the version before the change.

[dp]

LGTM. Nice refactoring!

[kosarev]

More of that would be great.

nit: These spaces after < here and below might need some more treatment.

Whoops. Fixed in 6b6303ac0024.
