Fenghua Yu 9599ec0471 x86-64, mem: Convert memmove() to assembly file and fix return value bug 
memmove_64.c only implements memmove() function which is completely written in
inline assembly code. Therefore it doesn't make sense to keep the assembly code
in .c file.

Currently memmove() doesn't store return value to rax. This may cause issue if
caller uses the return value. The patch fixes this issue.
