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.
