  From: Ezra Sitorus <ezra.sitorus@arm.com>

This patch is part of a series of patches implementing the _xN variants of the vld1 intrinsic for AArch32.
This patch adds the _x2 variants of the vld1 intrinsic. Tests use xN so that the latter variants (_x3, _x4) could be added.
The previous vld1_x2 has been updated to vld1q_x2 to take into account that it works with 4-word-length types. vld1_x2 is
now only for 2-word-length types.

ISA documents are at https://developer.arm.com/documentation/ddi0487/latest/

gcc/ChangeLog:
        * config/arm/arm_neon.h
        (vld1_u8_x2, vld1_u16_x2, vld1_u32_x2, vld1_u64_x2): New
        (vld1_s8_x2, vld1_s16_x2, vld1_s32_x2, vld1_s64_x2): New.
        (vld1_f16_x2, vld1_f32_x2): New.
        (vld1_p8_x2, vld1_p16_x2, vld1_p64_x2): New.
        (vld1_bf16_x2): New.
        (vld1q_types_x2): Updated to use vld1q_x2 from arm_neon_builtins.def
        * config/arm/arm_neon_builtins.def
        (vld1_x2): Updated entries.
        (vld1q_x2): New entries, but comes from the old vld1_x2
        * config/arm/neon.md (neon_vld1<VMEMX2_q>_x2<VDQX:mode>): Updated from neon_vld1_x2<mode>.

gcc/testsuite/ChangeLog:
        * gcc.target/arm/simd/vld1_base_xN_1.c: Add new tests.
        * gcc.target/arm/simd/vld1_bf16_xN_1.c: Add new tests.
