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.

The compiler OOMs when I try to use -ftime-report.

However, it runs about 10 minutes before it OOMs and the peak memory usage
prior to OOMing appears to be about 110 megs. So the compilation speed 
(or lack thereof) doesn't seem dependent on memory usage.

This also happened on h8300-hms last time I tried,
which is at least a few weeks ago.
(sorry for not reporting)

This is not SH specific, it's easily reproduced on any target I've tried it on 
(i686, ppc, hpux).

Mainline converts this to a memcpy from read-only storage.
Need to do the same trick in the gimplifier.
