compiler-builtins

Fork of compiler-builtin from rust for zynq, with fast memcpy function adapted from newlib. We have to fork it because the compiler-builtins would use their slow memcpy implementation for compiler intrinsics regardless if you provided you own memcpy. #253.

The memcpy function is in assembly with neon optimization.
