...
This saves a small amount of code size, and is a first small step toward
passing values on the stack across block boundaries.

[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.

[WebAssembly] Add -m:e to the target triple.
...
This enables ELF-style name mangling, which primarily means using ".L" for
private symbols.

[WebAssembly] Add type prefixes to call instructions
...
Add return type information to call and call_indirect instructions. This
allows them to be disambiguated without knowledge of the callee.
