aarch64: Add new vector mode V8DI
This patch is adding new V8DI mode which will be used with new Armv8.7-A
LS64 extension intrinsics.
gcc/ChangeLog:
* config/aarch64/aarch64-modes.def (VECTOR_MODE): New V8DI mode.
* config/aarch64/aarch64.c (aarch64_hard_regno_mode_ok): Handle
V8DImode.
* config/aarch64/iterators.md (define_mode_attr nunits): Add entry
for V8DI.
