[Bug middle-end/46076] [4.6 regression] constant propogation and compile-time math no longer happening versus 4.4 and 4.5

This is a reduction from proprietary (and complex) code, and the optimization
has regressed there as well. Any diagnosis on why it would have regressed and
not triggered a testsuite failure?
