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\!

the newly created allocas may be used by inlined calls, so these

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

Delete test/CodeGen/X86/stack-color-with-reg-2.ll, because its test
is extremely fragile and hard to meaningfully update.

the addressing modes don't make this trivially easy. This allows
it to avoid falling into the less precise heuristics in more
cases.
