[prange] Use type agnostic range in phiopt [PR115191]
Fix a use of int_range_max in phiopt that should be a type agnostic
range, because it could be either a pointer or an int.
PR tree-optimization/115191
gcc/ChangeLog:
* tree-ssa-phiopt.cc (value_replacement): Use Value_Range instead
of int_range_max.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/pr115191.c: New test.
