String: Split memcpy tests so that parallel build is faster
No bug. This commit splits test-memcpy.c into test-memcpy.c and test-memcpy-large.c. The idea is parallel builds will be able to run both in parallel speeding up the process. Signed-off-by: Noah Goldstein <goldstein.w.n@gmail.com> Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
