The change to make SCOPE_REFs value-dependent revealed a bug in our
handling of alias-template instantiations; we weren't pushing into the
context of the alias before substituting the type, and then we were
remembering the previously instantiated one when instantiating in a
different context.

If the only reference in a source file is to a static method of a class, then
GCC would output debug information for the class name but not any of its

It didn't take long to find a build problem with libbacktrace. I forgot
to back and retest the unknown cases after changing the way backtrace
state was handled. This patch should fix bootstrap. Tested on
x86_64-unknown-linux-gnu, which proves little since the file is not used
on that platform.
gfortran shouldn't simplify SCAN/VERIFY if the BACK= argument is present
but not a constant.
Build and regtested on x86-64-linux.
OK for the trunk?
