This will allow us to move expressions from one function to another, for
example when the parser determines that a given cover grammar instance
is actually the default value initializer for an arrow function.

Revert "Assign bailout and type feedback IDs in a post-pass"

This reverts r24757, which breaks the ARM64 simulator build.
Simple repro:
