The memcmp will be optimized further and even the pathological case
'strstr(x, "x") == x' generates optimal code now.

Pulled CodeMetrics out of InlineCost.h and made it a bit more general, so it can be reused from PartialSpecializationCost

Partial specialization was not checking the callsite to make sure it was using the same constants as the specialization, leading to calls to the wrong specialization.  Patch by Takumi Nakamura\!

fixes a bug where LSR was failing to recognize ICmpZero uses,
which led it to be unable to reverse the induction variable in the
