Update more rustc/libtest things for wasm64

Browse Source 
* Add wasm64 variants for inline assembly along the same lines as wasm32
* Update a few directives in libtest to check for `target_family`
  instead of `target_arch`
* Update some rustc codegen and typechecks specialized for wasm32 to
  also work for wasm64.
