Reimplement AArch64 TRN intrinsics with __builtin_shuffle.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/vtrns32.c: Expect zip[12] insn rather than trn[12].
	* gcc.target/aarch64/vtrnu32.c: Likewise.
	* gcc.target/aarch64/vtrnf32.c: Likewise.

gcc/ChangeLog:

	* config/aarch64/arm_neon.h (vtrn1_f32, vtrn1_p8, vtrn1_p16, vtrn1_s8,
	vtrn1_s16, vtrn1_s32, vtrn1_u8, vtrn1_u16, vtrn1_u32, vtrn1q_f32,

	vtrn2q_u32, vtrn2q_u64): Replace temporary asm with __builtin_shuffle.
