Fix wasm-related compile errors:

- Update `fail()` to not require a `srcLoc`.
This brings it in line with other backends, and we were always passing 'node_offset = 0', anyway.
- Fix unused local due to change of architecture wrt function/decl generation.
- Replace all old instructions to indexes within the function signatures.
