aarch64: Add LS64 extension and intrinsics
This patch is adding support for LS64 (Armv8.7-A Load/Store 64 Byte extension)
which is part of Armv8.7-A architecture. Changes include missing plumbing for
TARGET_LS64, LS64 data structure and intrinsics defined in ACLE. Machine
description of intrinsics is using new V8DI mode added in a separate patch.
__ARM_FEATURE_LS64 is defined if the Armv8.7-A LS64 instructions for atomic
64-byte access to device memory are supported.
New compiler internal type is added wrapping ACLE struct data512_t:
typedef struct {
uint64_t val[8];
} __arm_data512_t;
