[WebAssembly] Basic support for Wasm object file encoding.
...
With the "wasm32-unknown-unknown-wasm" triple, this allows writing out
simple wasm object files, and is another step in a larger series toward
migrating from ELF to general wasm object support. Note that this code
and the binary format itself is still experimental.

[WebAssembly] Add skeleton MC support for the Wasm container format
...
This just adds the basic skeleton for supporting a new object file format.
All of the actual encoding will be implemented in followup patches.

[WebAssembly] Implement more WebAssembly binary encoding.
...
This changes locals from being declared by the emitLocal hook in
WebAssemblyTargetStreamer, rather than with an instruction. After exploring
the infastructure in LLVM more, this seems to make more sense since
declaring locals doesn't use an encoded opcode.
This also adds more 0xd opcodes, type encodings, and miscellaneous
binary encoding bits.
