[Analysis] Clean up getPromotionCandidatesForInstruction (NFC) (#95624)

Callers of getPromotionCandidatesForInstruction pass NumVals as an out
parameter for the number of value-count pairs of the value profiling
data, but nobody uses the out parameter.

This patch removes the parameter and updates the callers.  Note that
the number of value-count pairs is still available via
getPromotionCandidatesForInstruction(...).size().
