re PR target/81325 (-fcompare-debug failure on ppc64le)

	PR target/81325
	* cfgbuild.c (find_bb_boundaries): Ignore debug insns in decisions
	if and where to split a bb, except for splitting before debug insn
	sequences followed by non-label real insn.  Delete debug insns
	in between basic blocks.

	* g++.dg/cpp0x/pr81325.C: New test.
