go -- misc/wasm, cmd/link: do not let command line arguments overwrite global data

The Go project reports:

When invoking functions from WASM modules, built using GOARCH=wasm
GOOS=js, passing very large arguments can cause portions of the module
to be overwritten with data from the arguments.
If using wasm_exec.js to execute WASM modules, users will need to
replace their copy after rebuilding any modules.
