This apparently breaks -fcompare-debug with -m32 so I have made it more robust
by means
This is a regression present on the mainline in the form of a -fcompare-debug
failure at -O3 on a compiler-generated testcase. Fixed by disregarding a
debug statement in the last position of a basic block to reset the current
location for the outgoing edges.
