This implements a new table-gen emitter to create tables for a wasm disassembler, and a dissassembler to use them. Comes with 2 tests, that tests a few instructions manually. Is also able to disassemble large .wasm files with objdump reasonably. Not working so well, to be addressed in followups: - objdump appears to be passing an incorrect starting point. - since the disassembler works an instruction at a time, and it is disassembling stack instruction, it has no idea of pseudo register assignments. These registers are required for the instruction printing code that follows. For now, all such registers appear in the output as $0.
