[Bug c++/87107] Template instantiation is 50x slower than with clang++

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87107 --- Comment #2 from Frédéric --- Yes, I've seen that one and saw it was fixed before 8.2.0. I wasn't sure actually if it was included in 8.2.0 as it was solved few weeks before 8.2.0 was out.
