re PR tree-optimization/76490 (when use -O2 -fcheck-founds compiler appears to hang and consumes all memory)

PR tree-optimization/76490
* tree-vrp.c (update_value_range): Preserve overflow infinities
when intersecting with ranges from get_range_info.
(operand_less_p): Handle overflow infinities correctly.
(value_range_constant_singleton): Use vrp_operand_equal_p
to handle overflow max/min correctly.
(vrp_valueize): Likewise.
(union_ranges): Likewise.
(intersect_ranges): Likewise.
(vrp_visit_phi_node): Improve iteration limitation to only
apply when we'll possibly re-visit the PHI via a changed argument
on the backedge.
* gfortran.fortran-torture/compile/pr76490.f90: New testcase.
* gcc.dg/pr52904.c: XFAIL.
