Note, I am not going to close this bug just yet because this testcase produces
some weird -O2 timing results for 4.2.0:
tree operand scan : 11.29 (27%) usr 0.51 (22%) sys 13.09 (25%) wall
9015 kB ( 4%) gg

In 4.2.0 on i686-linux-gnu this is much better:
parser: 1.99 (31%) usr 0.28 (28%) sys 2.42 (25%) wall
43674 kB (49%) ggc
name lookup : 0.48 ( 7%) usr 0.37 (37%) sys 1.51 (16%

Some updates: the -ftime-report problems were a local problem with apple's gcc,
now fixed. This testcase has some templates (e.g. the match stuff), but mostly
it is just big branchy compiler code :), not atypical of many C

I think this is just a problem of templates, lots of them.

Confirmed. The middle-end problems are almost all in reload.c.
For the profile, everything is just spread all around.
