Test-case modfied to take exponential time on trunk too.
It turns out that it was fast on trunk because inlining is less aggressive
there.
Making some functions inline causes compile time to blow up with trunk also.
Updated test case attached also.
PS. The correct fix for the rotate on trunk was to use
__builtin_ia32_psrldi/pslldi.
