gcc45-pr41241.patch

Untested fix for the cfgloopmanip.c issue.  We have (mem (mem (sp + cst))
in the debug_insn, and we weren't expecting/handling that.

Still, if sp is present in the debug_insn in some unexpected way, the
debug_insn will cause -fcompare-debug differences.  I think for DEBUG_INSN_P
we'll need to
queue them into a special list and replace all occurrences of sp with sp + cst.
