[AArch64] Implement vfma_f64, vmla_f64, vfms_f64, vmls_f64 intrinsics. 

[gcc/]
	* config/aarch64/arm_neon.h (vfma_f64): New intrinsic.
	(vmla_f64): Likewise.
	(vfms_f64): Likewise.
	(vmls_f64): Likewise.

[testsuite/]
	* gcc.target/aarch64/simd/vfma_f64.c: New test.
	* gcc.target/aarch64/simd/vmla_f64.c: Likewise.
	* gcc.target/aarch64/simd/vfms_f64.c: Likewise.
	* gcc.target/aarch64/simd/vmls_f64.c: Likewise.
