53ff96ab08 [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.

d73b41ae22 [WebAssembly] Define WebAssembly-specific relocation codes.
Currently WebAssembly has two kinds of relocations; data addresses and
function addresses. This adds ELF relocations for them, as well as an
MC symbol kind to indicate which type of relocation is needed.

251dff3d1b [WebAssembly] Add WebAssemblyMCInstLower.cpp.
This isn't used yet; it's just a start towards eventually using MC to
do instruction printing, and eventually binary encoding.
