  [LV][VPlan] Remove any-of reduction from precomputeCost. NFC (#117109)

The any-of reduction contains phi and select instructions. 

The select instruction might be optimized and removed in the vplan which
may cause VF difference between legacy and VPlan-based model. But if the
select instruction be removed, `planContainsAdditionalSimplifications()`
will catch it and disable the assertion.

Therefore, we can just remove the ayn-of reduction calculation in the
precomputeCost().
