[Bug c++/42336] [4.5 Regression] ICE with pointer-to-member-function argument in template function

It basically seems to me that the modifications made by
ipa_modify_formal_parameters are incompatible with proper debugging
information; the method is still a method as far as the language is concerned
even if the actual code generated optimizes away the this pointer.

I think it would be better to represent those sorts of modifications via
cloning rather than by modifying the primary decls.
