[Bug c++/42336] [c++0x] ICE with pointer-to-member-function decltype argument in template function

["jason at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The problem here is that after we're done parsing the translation unit, we do
IPA optimizations, and IPA decides to change the type of X::func from a
METHOD_TYPE to a FUNCTION_TYPE.

Then later we're emitting debug information about b<X>, and ask the compiler
for that name.  So we try to substitute X into decltype(&T::func) to see if the
argument we have is the same as the default argument.  But at this point
T::func resolves to a function with FUNCTION_TYPE, whereas we were expecting
one with METHOD_TYPE, and boom.

I suppose we can't do any tsubsting after IPA runs.
