This commit adds JavaScript util code to utils to support the wasm
backend's JSFFI functionality:
- jsffi/post-link.mjs, a post-linker to process the linked wasm module
and emit a small complement JavaScript ESM module to be used with it
at runtime
- jsffi/prelude.js, a tiny bit of prelude code as the JavaScript side
of runtime logic
- jsffi/test-runner.mjs, run the jsffi test cases

bindist libdir, so when using the wasm backend's JSFFI feature, the

This commit adds opts.target_wrapper which allows overriding the
target wrapper on a per test case basis when testing a cross target.
This is used when testing the wasm backend's JSFFI functionality; the
rest of the cases are tested using wasmtime, though the jsffi cases
are tested using the node.js based test runner.

sub-word sized integers.
