[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.
