aarch64: Handle overlapping registers in movv8di [PR113550]
The LS64 movv8di pattern didn't handle loads that overlapped with
the address register (unless the overlap happened to be in the
last subload).
gcc/
PR target/113550
* config/aarch64/aarch64-simd.md: In the movv8di splitter, check
whether each split instruction is a load that clobbers the source
address. Emit that instruction last if so.

PR target/113550
* gcc.target/aarch64/pr113550.c: New test.
