I'm not so sure about it. In my opinion it is a gcc bug. 2u and 2 are
literals of different types. But I'm not a C++ expert.
It looks like g++ and clang treat C++ language differently in this case.
I've asked on stackoverflow:
https://stackoverflow.com/questions/48594693/auto-template-parameters-g-7-3-vs-clang-6-0-which-compiler-is-correct
If Clang is correct here, than foo<1u> and foo<1> are two different types.
And so gcc should emit correct postfixes to debuginfo.
