[pushed] aarch64: Disassociate ls64 from simd
Commit Message
The ls64-related move expanders and splits required TARGET_SIMD.
That isn't necessary, since the 64-byte values are stored entirely
in GPRs. (The associated define_insn was already correct.)
I wondered about moving the patterns to aarch64.md, but it wasn't
clear-cut.
Tested on aarch64-linux-gnu & pushed.

gcc/
* config/aarch64/aarch64-simd.md (movv8di): Remove TARGET_SIMD
condition. Likewise for the related define_split. Tweak formatting.
gcc/testsuite/
* gcc.target/aarch64/acle/ls64_asm_2.c: New test.
