  Log Message:
  -----------
  [SLP][NFCI]Improve compile time for phis with large number of incoming values.

Added a limit of 128 incoming values at max for PHIs nodes to be
vectorized plus improved performance by using logarithmic search instead
of linear if the number of incoming values is > 4.
