[PATCH AArch64] Removed unused get_lane and dup_lane builtins.


None of the variants of __builtin_aarch64_get_lane or __builtin_aarch64_dup_lane are used in arm_neon.h (vdup_lane uses vget_lane and vdup_n, vget_lane uses be_checked_get_lane to do an endianness swap, vdup_n uses gcc vector extension code). So remove them.

Regression tested on aarch64-none-elf.

gcc/ChangeLog:

	* gcc/config/aarch64/aarch64-simd-builtins.def
	(dup_lane, get_lane): Delete.
