reassoc: Fix up recent regression in optimize_range_tests_cmp_bitwise [PR106958]

As the following testcase reduced from glibc fmtmsg.c shows
(it doesn't ICE on x86_64/i686 unfortunately, but does on various other
arches), my last optimize_range_tests_cmp_bitwise change wasn't fully
correct.  The intent was to let all pointer operands be cast to
pointer_sized_int_node first in addition to the other casts (to type1)
which are done for id >= l cases.
But one spot I've touched used always cast to type1 (note, the (b % 4) == 3
case is impossible for pointer operands because that is for !TYPE_UNSIGNED
operands and pointers are TYPE_UNSIGNED) and in the other spot the cast
would be done only for id >= l if not useless, but for pointers we need
to cast it always.

	PR tree-optimization/106958
	* tree-ssa-reassoc.cc (optimize_range_tests_cmp_bitwise): If
	id >= l, cast op to type1, otherwise to pointer_sized_int_node.
	If type has pointer type, cast exp to pointer_sized_int_node
	even when id < l.

	* gcc.c-torture/compile/pr106958.c: New test.
