Subject: [Bug optimization/13798] New: 10x compile time regression

Here are the compile times for imdecode.i (from stress-1.17) using the options
-O2 -m4 on a P2/300 with 128 megs of RAM:

tree-ssa:

real    23m56.505s
user    22m42.970s
sys     0m11.900s

mainline:

real    2m9.078s
user    2m5.930s
sys     0m1.970s

This appears to be a 10x compile time regression.
