phiopt: Fix up two_value_replacement BOOLEAN_TYPE handling for Ada [PR98188]

For Ada with LTO, boolean_{false,true}_node can be 1-bit precision boolean,
while TREE_TYPE (lhs) can be 8-bit precision boolean and thus we can end up
with wide_int mismatches.

This patch for non-VR_RANGE just use VARYING min/max manually.
The min + 1 != max check will then do the rest.

	PR bootstrap/98188
	* tree-ssa-phiopt.c (two_value_replacement): Don't special case
	BOOLEAN_TYPEs for ranges, instead if get_range_info doesn't return
	VR_RANGE, set min/max to wi::min/max_value.
