chacha: Move x86-64 CPU & length dispatching from assembly to C. The x86-64 and x86 code both have 4x and 1x SSSE3 code paths. Only the x86-64 version is modified here. (For 32-bit x86, it looks like it would be much harder to separate the 1x and 4x code paths into separate functions and there's little motivation to do so. So it is likely that 32-bit x86 would define |CHACHA20_ASM_SSSE3| without |CHACHA20_ASM_SSSE3_4X|.)

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.
