Message:

Add API to generate and consume cached bytecode
​https://bugs.webkit.org/show_bug.cgi?id=193401
<rdar://problem/47514099>

Reviewed by Keith Miller.

Add the generateBytecode and generateModuleBytecode functions to
generate serialized bytecode for a given SourceCode. These functions
will eagerly generate code for all the nested functions.

Additionally, update the API methods in JSScript to generate and use the
bytecode when the bytecodeCache path is provided.
