  InstCombine: Avoid counting uses of constants (#136566)

Logically it does not matter; getFreelyInvertedImpl doesn't
depend on the value for the m_ImmConstant case.

This use count logic should probably sink into getFreelyInvertedImpl,
every use of this appears to just be a hasOneUse or hasNUse count,
so this could change to just be a use count threshold.
