Add _FPU_MASK_RM and use it instead of FE_TOWARDZERO.

2014-06-24  Wilco  <wdijkstr@arm.com>

	* sysdeps/arm/fpu_control.h (_FPU_MASK_RM): Define.
	* sysdeps/arm/fenv_private.h (libc_fesetround_vfp)
	(libc_feholdexcept_setround_vfp) (libc_feholdsetround_vfp)
	(libc_feresetround_vfp) (libc_feholdsetround_vfp_ctx)
	(libc_feresetround_vfp_ctx): Use _FPU_MASK_RM.
	* sysdeps/arm/fesetround.c (fesetround): Use _FPU_MASK_RM.
	* sysdeps/arm/get-rounding-mode.h (get_rounding_mode):
	Use _FPU_MASK_RM.
