c++: explain failing static_assert

While looking at another bug I wanted the compiler to tell me what the two
unequal values were.

gcc/cp/ChangeLog:

* semantics.cc (find_failing_clause): Return expr if not
decomposable.
(finish_static_assert): Show constant values in failing
comparison.

gcc/testsuite/ChangeLog:

* g++.dg/template/explicit-args6.C: Add expected message.
