Hello,

Lots of changes yesterday produced new regressions in C, C++, Fortran
and mudflap. I think I know what the mudflap problem is, so I'll take
care of that. Could you folks take a look at the new regressions and
see if they're related to your changes?
FAIL: gcc.dg/tree-ssa/20030814-4.c scan-tree-dump-times set = -1 0

OK.  After looking at these some more.  These are failures that are a
combination of the COND_EXPR lowering and some sillyness in PRE.

this patch adds a cfg-aware version of remove_useless_..., thus fixing these failures.

Thanks a bunch Zdenek. I really appreciate it.
I'm going to retest the load PRE patch i posted a few days ago, and commit it after i get test results.
