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. ports/ChangeLog.arm: 2013-09-16 Will Newton <will.newton@linaro.org> * sysdeps/arm/armv7/multiarch/memcpy_impl.S: Tighten check on entry to aligned copy loop to improve performance.
