re PR go/91617 (Many go test case failures after r275026)

PR go/91617
* fold-const.c (range_check_type): For enumeral and boolean
type, pass 1 to type_for_size langhook instead of
TYPE_UNSIGNED (etype).  Return unsigned_type_for result whenever
etype isn't TYPE_UNSIGNED INTEGER_TYPE.
(build_range_check): Don't call unsigned_type_for for pointer types.
* match.pd (X / C1 op C2): Don't call unsigned_type_for on
range_check_type result.
