  Log Message:
  -----------
  [AMDGPU][AsmParser] Introduce MC representation for lit() and lit64(). (#160316)

And rework the lit64() support to use it.

The rules for when to add lit64() can be simplified and
improved. In this change, however, we just follow the existing
conventions on the assembler and disassembler sides.

In codegen we do not (and normally should not need to) add explicit
lit() and lit64() modifiers, so the codegen tests lose them. The change
is an NFCI otherwise.

Simplifies printing operands.
