* tree.h (build_uniform_cst, uniform_integer_cst_p): Declare.
* tree.c (build_uniform_cst, uniform_integer_cst_p): New functions.
* match.pd (define_predicates): Add uniform_integer_cst_p.
(cmp @0 INTEGER_CST@1, cmp (convert?@2 @0) INTEGER_CST@1): Adjust
so that it works also for vector comparisons with uniform constants
with INTEGER_CST element.
* g++.dg/tree-ssa/pr88152-1.C: New test.
