[patch] KFAIL gdb/1025

[David Carlton <carlton@math.stanford.edu>]

I've been seeing some repeatable failures in gdb.c++/ovldbreak.exp;
this patch KFAILs them, according to PR gdb/1025 that I just filed.

Strangely enough, I'm seeing more failures than Michael does; he only
sees 4, and those only with i686-pc-linux-gnu/GCC2.95.3/DWARF-2; I'm
seeing 6 with i686-pc-linux-gnu/GCC3.{1,2}/DWARF2.  I don't know
what's weird about my setup.  (For all I know, GCC might even be doing
optimization that it shouldn't; it's not entirely clear to me from
skimming the assembly code.)

I've committed the attached patch.

	'might_kfail' arg.
	KFAIL some of the continue_to_bp_overloaded calls, according to
	PR c++/1025.
