arm-cores.def (arm1156t2-s, [...]): Use v6t2 tuning. 

gcc/
	* arm-cores.def (arm1156t2-s, arm1156t2f-s): Use v6t2 tuning.
	(cortex-a5, cortex-a8, cortex-a15, cortex-r4, cortex-r4f, cortex-m4)
	(cortex-m3, cortex-m1, cortex-m0): Use cortex tuning.
	* config/arm/arm-protos.h (tune_params): Add prefer_constant_pool
	field.
	* config/arm/arm.c (arm_slowmul_tune, arm_fastmul_tune)
	(arm_xscale_tune, arm_9e_tune, arm_cortex_a9_tune)
	(arm_fa726te_tune): Add prefer_constant_pool setting.
	(arm_v6t2_tune, arm_cortex_tune): New.
	* config/arm/arm.h (TARGET_USE_MOVT): Make dependent on
	prefer_constant_pool setting.
