b5142e044f Use SSE2 intrinsics header in sse_simd.cpp only if needed (#759) 
Embarcadero C++Builder v10.3 [has a bug](https://quality.embarcadero.com/browse/RSP-22883) where its old Intel intrinsics headers try to use retired Clang builtins and fail to compile. In devising a workaround with `-DCRYPTOPP_DISABLE_ASM`, I found that `sse_simd.cpp` includes `<emmintrin.h>` even when its code doesn't need the intrinsics.

With this patch, `-DCRYPTOPP_DISABLE_ASM` will be a sufficient workaround because `CRYPTOPP_SSE2_INTRIN_AVAILABLE` is derived from it in `config.h`.

Hugh, interesting.

Thank you very much.

Ping @randombit. Botan may want or need this, too.

Fix the cut-in of Moon's implementation (GH #761) 
The initial cut-in was missing preamble present in Moon's curve25519_donna function. It originally tested good because we only perform a pairwise consistency check in release builds. Comprehensive testing with debug builds revealed the problem. Debug builds cross-validate against Bernstein's TweetNaCl library.

Add Moon's curve25519 using SSE2 (GH #761) 
Moon's code is very fast. In fact it is so fast it broke our benchmarks. Moon's code registers 0.00 milliseconds and 0.00 megacycles/operation.
