Subject: [PATCH 16/35] [Backport] phiopt: Use gphi *phi instead of gimple *phi
 some more

Reference: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=cfd65e8d5299a7cf7d2ecd92b0e24ea4cfb697d9

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 *.
