Dan Gohman 7d7409e553 [WebAssembly] Convert the remaining unit tests to the new wasm-object-file target.
To facilitate this, add a new hidden command-line option to disable
the explicit-locals pass. That causes llc to emit invalid code that doesn't
have all locals converted to get_local/set_local, however it simplifies
testwriting in many cases.

Dan Gohman b7c2400fa7 [WebAssembly] Optimize away return instructions using fallthroughs.
This saves a small amount of code size, and is a first small step toward
passing values on the stack across block boundaries.

Dan Gohman 26c6765bd6 [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.

Dan Gohman 0c6f5ac50a [WebAssembly] Add -m:e to the target triple.
This enables ELF-style name mangling, which primarily means using ".L" for
private symbols.

Dan Gohman c7c0445443 [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.
