Dan Gohman d934cb8806 [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.

Derek Schuff 732636d901 [WebAssembly] Check return value of getRegForValue in FastISel 
Previously, FastISel for WebAssembly wasn't checking the return value of
`getRegForValue` in certain cases, which would generate instructions
referencing NoReg. This patch fixes this behavior.
