PR c++/8570 line number in error message is badly placed with illegal template friend declaration

["Manuel López-Ibáñez" <lopezibanez at gmail dot com>]

:ADDPATCH c++:

The problem here is that input_location points to the start of the
declaration of the class instead of the point where the friend
template is being declared.

bootstrapped and regression tested with --enable-languages=all on
x86_64-unknown-linux-gnu

OK to commit?
