Add an option to disable SSE2 intrinsics for testing. We have some code which uses SSE2 intrinsics which, since they don't have complicated build requirements, is enabled even with OPENSSL_NO_ASM. x86_64 mandates SSE2 and people building for x86 tend to mandate it anyway these days. This is great, but we still have generic 32-bit and 64-bit code configurations for other platforms. 32-bit generic code is covered by testing 32-bit ARM with NEON disabled. However, 64-bit ARM always has NEON available, so we have no SIMD-less 64-bit platforms in our CI. The immediate motivation is some bitsliced AES code I'm working on, however I believe this also applies to the existing HRSS code. This also fixes the HRSS feature checks to only look at __SSE2__, not __SSE__. __SSE__ isn't sufficient and we don't compile if GCC or Clang is told -msse -mno-sse2.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
