An interesting "optimization"? for __glibcxx_assert under verbose mode

[unlvsur unlvsur]

I think the parameter can be just embedded in the symbol name of the function. This improves code gen and make optimizers happier under -Os.

But it only works under C++20.

This is a proven concept. It works for both gcc and clang
