* gimple-ssa-strength-reduction.c (all_phi_incrs_profitable): Fail
the optimization if a PHI or any of its arguments is not dominated
by the candidate's basis. Use gphi* rather than gimple* as
appropriate.
(replace_profitable_candidates): Clean up a gimple* variable that
should be a gphi* variable.
