The calls to fwrite/fread can be very expensive. GCC avoids this by using a
buffer to read and write from the file, thus limiting the number of fwrite/fread
calls.

- Add memcpy and memcmp to the stub headers.
- __uint128_t is not available on 32 bit platforms. It's also unused so just

- Motivation is explained in the README, but basically it is convenient to be
able to build compiler-rt free standing. Since our external dependencies are
so small, we can achieve this relatively easily by just stubbing out the
declarations of the external dependencies.
- This is in no way, shape, or form intended to be complete, it is just the
minimal stubs necessary to support the stuff we use.
