Add ABI testing for 32-bit x86. This is much less interesting (stack-based parameters, Windows and SysV match, no SEH concerns as far as I can tell) than x86_64, but it was easy to do and I'm more familiar with x86 than ARM, so it made a better second architecture to make sure all the architecture ifdefs worked out. Also fix a bug in the x86_64 direction flag code. It was shifting in the wrong direction, making give 0 or 1<<20 rather than 0 or 1. (Happily, x86_64 appears to be unique in having vastly different calling conventions between OSs. x86 is the same between SysV and Windows, and ARM had the good sense to specify a (mostly) common set of rules.) Since a lot of the assembly functions use the same names and the tests were written generically, merely dropping in a trampoline and CallerState implementation gives us a bunch of ABI tests for free.

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.
