only print the template instantiation backtrace for the first error.
Also, if a base class has failed to type-check during instantiation,
just drop that base class and continue on to check other base classes.

'struct A<double, int>'
In the "template instantiation depth exceeded" message, print
"-ftemplate-depth-N" rather than "-ftemplate-depth=N".
An unnamed tag type that is declared with a typedef, e.g.,
typedef struct { int x, y; } Point;
can be used as a template argument. Allow this, and check that we get
sensible pretty-printing for such things.

to a diagnostic that will be invoked after the diagnostic (if it is
not suppressed). The hooks are allowed to produce additional
diagnostics (typically notes) that provide more information. We should
be able to use this to help diagnostic clients link notes back to the
diagnostic they clarify. Comments welcome; I'll write up documentation
and convert other clients (e.g., overload resolution failures) if
there are no screams of protest.
As the first client of post-diagnostic hooks, we now produce a
template instantiation backtrace when a failure occurs during template
instantiation. There's still more work to do to make this output
pretty, if that's even possible.
