Scan modules that only exist in a savestate for functions

A module the game loaded before the state was saved, but that this run never loaded, was never
scanned, so loading such a state left all of its code without function replacements and hooks
(and without functions in the debugger). Scan any loaded module with no analyzed functions in its
text range before rehashing.
