cmd/compile: add sign-extension operators on wasm
This change adds the GOWASM option "signext" to enable
the generation of experimental sign-extension operators.
The feature is in phase 4 of the WebAssembly proposal process:
https://github.com/WebAssembly/meetings/blob/master/process/phases.md
More information on the feature can be found at:
