This patch adds basic support to AsmParser which can handle basic
instructions with register or immediate operands. With the addition of
the parser, now it's possible to test instructions encoding with `llvm-mc`.
So we remove those `.mir` testcases in CodeGen. See D115862 <https://reviews.llvm.org/D115862> for more
details.

Disassembler will be added later and then we can do `round-trip` test.
