gcc45-pr43290.patch
Updated patch. This one includes testcases, and also fixes for -O+, when
optimizing we really shouldn't be replacing random registers that once happened
to be vDRAP or DRAP somewhere with DW_OP_fbreg and there is no point tracking
it at all - after all when optimizing combiner or some other optimization pass
will very likely remove the vDRAP = DRAP insn anyway. For -O1+ var-tracking is
supposed to do the right job finding where the variable lives.
