[PATCH, ARM] memcpy fix for unaligned access

Subject: [PATCH, ARM] memcpy fix for unaligned access

This patch fixes a bug in memcpy when buffers are not word-aligned and
unaligned access is enable in hardware. 

This bug caused regression test failures in
gcc.c-torture/execute/memcpy-2.c. The bug went undetected in my previous
regression runs, because unaligned access was disabled in my build
configuration. 

No regression on qemu --with-cpu cortex-a9 --with-thumb.

Thank you,
Greta
