Commit r191484 treated constexpr function templates as normal function templates with respect to delaying their parsing. However, this is unnecessarily restrictive because there is no compatibility concern with constexpr, MSVC doesn't support it. Instead, simply disable delayed template parsing for constexpr function templates. This largely reverts the changes made in r191484 but keeps it's unit test. This fixes PR17661. llvm-svn: 193274
