Subject: asm2wasm i64 support (#723)

* support i64 intrinsics from fastcomp, adding --wasm-only flag

* refactor callImport logic in asm2wasm to avoid recomputing wasm types again

* legalize illegal i64 params in exports and imports

* do safe i64 binary ops depending on precision

* fix addVar, only assert on names if we are using a name
