Ricky Taylor 8301d3efae [M68k] Implement AsmParser
This is a work-in-progress implementation of an assembler for M68k.

Outstanding work:
- Updating existing tests assembly syntax
- Writing new tests for the assembler (and disassembler)

I've left those until there's consensus that this approach is okay (I hope that's okay!).

Questions I'm aware of:
- Should this use Motorola or gas syntax? (At the moment it uses Motorola syntax.)
- The disassembler produces a table at runtime for disassembly generated from the code beads. Is this okay? (This is less than ideal but as I mentioned in my llvm-dev post, it's quite complicated to write a table-gen parser for code beads.)

; At the moment, all encoding tests for M68k live in llvm/test/CodeGen/M68k/.
; This is the first test included as part of the AsmMatcher and lacks encoding checks.
; The current migration plan is to consolidate all of the encoding tests in this
; directory along with AsmMatcher/ Disassembler tests like the other platforms.
; For more information and status updates see bug #49865.
