Vedant Kumar 15718a6190 [CodeExtractor] Erase debug intrinsics in outlined thunks (fix PR22900) ...

Variable updates within the outlined function are invisible to
debuggers. This could be improved by defining a DISubprogram for the
new function. For the moment, simply erase the debug intrinsics instead.

This fixes verifier failures about function-local metadata being used in
the wrong function, seen while testing the hot/cold splitting pass.
