* gcc.c-torture/execute/pr55875.c: New testcase.
* g++.dg/torture/pr55875.C: New testcase.
* tree-ssa-loop-niter.c (number_of_iterations_cond): Add
EVERY_ITERATION parameter.
(number_of_iterations_exit): Check if exit is executed every
iteration.
(idx_infer_loop_bounds): Similarly here.
(n_of_executions_at_most): Simplify
to only test for cases where statement is dominated by the
particular bound; handle correctly the "postdominance"
test.
(scev_probably_wraps_p): Use max loop iterations info
as a global bound first.
