[Bug optimization/13479] New: [3.4 regression] 20-30% compile-time regression with template-heavy code

["giovannibajo at libero dot it" <gcc-bugzilla at gcc dot gnu dot org>]

I attacched three preprocessed files for 3.2, 3.3 and 3.4. Compile times on my 
machine are as follows

        3.2    3.3    3.4

-O0     16.0s  14.9s  17.5s  +17%
-O1     20.7s  19.5s  23.2s  +18%
-O2     25.0s  23.6s  32.2s  +36%
-O3     27.3s  27.5s  34.2s  +24%

I am using 3.2.2, 3.3.1, 3.4 CVS 20031203.
This is better than PR8361, but still a big regression. I didn't test tree-ssa.
