[interpreter] Compiler shortcut when bytecode present.

[interpreter] Compiler shortcut when bytecode present.

This adds a shortcut to the compilation pipeline that makes sure we are
not regenerating bytecode when it has been preserved from a previous
request. This can happen when code flushing removes baseline code,
thereby clearing the entry trampoline but leaving bytecode intact.
