  1. Add some unstable target features for the wasm target codegen 

    I was experimenting with cross-language LTO for the wasm target recently
between Rust and C and found that C was injecting the `+mutable-globals`
flag on all functions. When specifying the corresponding
`-Ctarget-feature=+mutable-globals` feature to Rust it prints a warning
about an unknown feature. I've added the `mutable-globals` feature plus
another few I know of to the list of known features for wasm targets.
These features all continue to be unstable to source code as they were
before.
