phiopt: Use gphi *phi instead of gimple *phi some more

Various functions in phiopt are also called with a gphi * but use
gimple * argument for it.

2021-05-06  Jakub Jelinek  <jakub@redhat.com>

	* tree-ssa-phiopt.c (value_replacement, minmax_replacement,
	abs_replacement, xor_replacement,
	cond_removal_in_popcount_clz_ctz_pattern,
	replace_phi_edge_with_variable): Change type of phi argument from
	gimple * to gphi *.
