target-supports.exp (add_options_for_arm_v8_neon): Add -march=armv8-a when we use v8 NEON.

2013-04-05  Kyrylo Tkachov  <kyrylo.tkachov@arm.com>

	* lib/target-supports.exp (add_options_for_arm_v8_neon):
	Add -march=armv8-a when we use v8 NEON.
	(check_effective_target_vect_call_btruncf): Remove arm-*-*-*.
	(check_effective_target_vect_call_ceilf): Likewise.
	(check_effective_target_vect_call_floorf): Likewise.
	(check_effective_target_vect_call_roundf): Likewise.
	(check_vect_support_and_set_flags): Remove check for arm_v8_neon.
	* gcc.target/arm/vect-rounding-btruncf.c: New testcase.
	* gcc.target/arm/vect-rounding-ceilf.c: Likewise.
	* gcc.target/arm/vect-rounding-floorf.c: Likewise.
	* gcc.target/arm/vect-rounding-roundf.c: Likewise.
