Hi Andrew,
This change will prevent the caller(s) of mips_mdebug_frame_id from
infinite-looping when we get badly lost on the stack frame.

* mips-tdep.c (mips_mdebug_frame_cache): Call error to prevent
infinite looping by caller.
(heuristic_proc_start): Warning() already prefixes "Warning: ".
Since I have some patches to make this "I'm not sure how" case into a
working part of the unwinder, I don't much like this. They got hung up
on the question of how to trust proc_desc's when we might be in the
prologue.
One time where this case occurs is in backtracing from a NULL pointer
dereference, which happens in the GDB testsuite now.
