[PATCH][Testsuite]Use user defined memmove in gcc.c-torture/execute/builtins/memops-asm-lib.c
After the change r249278. bcopy is folded into memmove. And in newlib
aarch64 memmove implementation, it will call memcpy in certain conditions.
The memcpy defined in memops-asm-lib.c will abort when the test is running.
A user defined memmove function is defined to bypass the library one.
So that memcpy won't be called accidentally.
gcc/testsuite/
* gcc.c-torture/execute/builtins/memops-asm-lib.c (my_memmove): New.
* gcc.c-torture/execute/builtins/memops-asm.c (memmove): Declare memmove.
