[ARM][2/4] Replace casts of 1 to HOST_WIDE_INT by HOST_WIDE_INT_1 and HOST_WIDE_INT_1U

* config/arm/arm.md (andsi3): Replace cast of 1 to HOST_WIDE_INT
	with HOST_WIDE_INT_1.
	(insv): Likewise.
	* config/arm/arm.c (optimal_immediate_sequence): Replace cast of
	1 to unsigned HOST_WIDE_INT with HOST_WIDE_INT_1U.
	(arm_canonicalize_comparison): Likewise.
	(thumb1_rtx_costs): Replace cast of 1 to HOST_WIDE_INT with
	HOST_WIDE_INT_1.
	(thumb1_size_rtx_costs): Likewise.
	(vfp_const_double_index): Replace cast of 1 to unsigned
	HOST_WIDE_INT with HOST_WIDE_INT_1U.
	(get_jump_table_size): Replace cast of 1 to HOST_WIDE_INT with
	HOST_WIDE_INT_1.
	(arm_asan_shadow_offset): Replace cast of 1 to unsigned
	HOST_WIDE_INT with HOST_WIDE_INT_1U.
	* config/arm/neon.md (vec_set<mode>): Replace cast of 1 to
	HOST_WIDE_INT with HOST_WIDE_INT_1.
