Reviewed by Justin Michaud.

Adds --bbqAllowlist and --omgAllowlist options to the JSC command line.
Like existing allowlist options, these take either the single function
to allow compilation of, or a path to a file containing one allowed
function per line. Since WASM doesn't necessarily keep names in source,
and we don't currently employ the same function hashing technique we do
in JS, allowed functions are currently specified by function index.
