[ARM][3/4] Cleanup casts from INTVAL to [unsigned] HOST_WIDE_INT

	* config/arm/arm.md (ashldi3): Replace comparison of INTVAL of
	operands[2] against 1 with comparison against CONST1_RTX.
	(ashrdi3): Likewise.
	(lshrdi3): Likewise.
	(ashlsi3): Replace cast of INTVAL to unsigned HOST_WIDE_INT with
	UINTVAL.
	(ashrsi3): Likewise.
	(lshrsi3): Likewise.
	(rotrsi3): Likewise.
	(define_split above *compareqi_eq0): Likewise.
	(define_split above "prologue"): Likewise.
	* config/arm/arm.c (thumb1_size_rtx_costs): Likewise.
	* config/arm/predicates.md (shift_operator): Likewise.
	(shift_nomul_operator): Likewise.
	(sat_shift_operator): Likewise.
	(thumb1_cmp_operand): Likewise.
	(const_neon_scalar_shift_amount_operand): Replace manual range
	check with IN_RANGE.
	* config/arm/thumb1.md (define_peephole2 above *thumb_subdi3):
	Replace cast of INTVAL to unsigned HOST_WIDE_INT with UINTVAL.
