aarch64: Fold vget_low_* intrinsics to BIT_FIELD_REF [PR102171]
This patch folds vget_low_* intrinsics to BIT_FILED_REF to open up more
optimization opportunities for gimple optimizers.
While we are here, we also remove the vget_low_* definitions from arm_neon.h and
use the new intrinsics framework.
PR target/102171

* config/aarch64/aarch64-builtins.cc (AARCH64_SIMD_VGET_LOW_BUILTINS):
New macro to create definitions for all vget_low intrinsics.

gcc/testsuite/ChangeLog:
* gcc.target/aarch64/pr113573.c: Replace __builtin_aarch64_get_lowv8hi
with vget_low_s16.
* gcc.target/aarch64/vget_low_2.c: New test.
