rs6000: Fix creation of VEC_COND_EXPR
gcc/ChangeLog:
* config/rs6000/rs6000-call.c (fold_build_vec_cmp):
Since 502d63b6d6141597bb18fd23c87736a1b384cf8f, first argument
of a VEC_COND_EXPR cannot be tcc_comparison and so that
a SSA_NAME needs to be created before we use it for the first
argument of the VEC_COND_EXPR.
(fold_compare_helper): Pass gsi to fold_build_vec_cmp.
