[Bug middle-end/38074] New: [4.4 Regression] missed inlining since IRA merge on Core2 Duo

[dominiq at lps dot ens dot fr]

With gfortran 4.3.2 the functions ddx and ddy in the channel.90 polyhedron test
with:

gfortran -S -m64 -O3 -ffast-math -finline-limit=312 channel.f90

but not for -finline-limit=311.

Since the IRA merge, this is no longer the case even if I use
-finline-limit=6000. This causes a ~5% increase in the execution time (~2.4s
compared to ~2.3s, small but noticeable).

I suspect the same is true for the fatigue.f90 test.
