[PATCH] [AArch64] Inline memcpy() as a sequence of ldp-stp with 64-bit registers

[Sergey Dmitrouk]

Custom instruction scheduler (actually, both pre-RA and post-RA might be needed) might be a solution, but it replaces generic scheduler, which will only make scheduling worse.

No more ideas, looks like such instruction interleaving can't be achieved in LLVM with reasonable effort.
