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`.
