My last commit included an unused static function that caused
a -Wunused-function warning/error. I removed the function in
r255036 to unblock the bootstrap while retesting everything
in the meanwhile.

This uses static_assert to improve the errors when attempting to
instantiate invalid specializations of containers, e.g. set,

order of the hasher and equality predicate arguments).

- In many cases the copyright notice has "This file is part of the GNU
Fortran 95 runtime library (libgfortran)." It's a while since we've
called ourselves "GNU Fortran 95", so just remove the "95".

This is a patch from James that has been sitting in bugzilla for a few
weeks. The bug is that mips_register_frame_header_opt registers
the pass from a static variable which has an automatic variable in the

properly, bu

Hi!
During the first loop iteration, n is uninitialized, so testing
n.base_addr is wrong. Testing
(i == first ? this_n.base_addr : n.base_addr) is overkill,
perform_symbolic_merge will fail if some iterations have base_addr
set and others don't.
