I've adjusted range-ops so that EVRP will recognize that
c |= 1
is a non-zero range, and I've added a test case to check it.
The rest of this PR involves exposing ranges in a better way to fold-const.

The testcase is now optimized early during evrp after r255201. We still don't
record temporary ranges in SSA range info but we can perform the unreachable ()
trick VRP has.

The interesting bit is that during the stmt folding
/* For integral types with undefined overflow and C != 0 fold
x * C EQ/NE y * C into x EQ/NE y. */
(for cmp (eq ne)
