This is surely not valid code.
valid but undefined.

I wonder if the problem is the new call to force_gimple_operand. We now have:

doing some benchmarks on attached file (preprocessed source), i found, that
gcc-4.4 is somehow (in my case about 4%) slower than gcc-4.3 on x86_64, tuned
for core2:
code compiled with -O3 -march=core2
versions:
g++-4.3 -v
Using built-in specs.
Target: x86_64-linux-gnu

It was not fixed by the cfglayout changes. In fact tree switch conversion
makes the code even worse even though we don't need it really.

That patch isn't supposed to make any difference, because of when the parallel
is removed - it's not supposed to be early enough to affect where things are
passed. It just happens within the function.
