ARM: Improve armv7 memcpy performance.
Only enter the aligned copy loop with buffers that can be 8-byte
aligned. This improves performance slightly on Cortex-A9 and
Cortex-A15 cores for large copies with buffers that are 4-byte
aligned but not 8-byte aligned.

* sysdeps/arm/armv7/multiarch/memcpy_impl.S: Tighten check
on entry to aligned copy loop to improve performance.
