Add test of assembly code dispatch.

The first attempt involved using Linux's support for hardware
breakpoints to detect when assembly code was run. However, this doesn't
work with SDE, which is a problem.

This version has the assembly code update a global flags variable when
it's run, but only in non-FIPS and non-debug builds.

Update-Note: Assembly files now pay attention to the NDEBUG preprocessor
symbol. Ensure the build passes the symbol in. (If release builds fail
to link due to missing BORINGSSL_function_hit, this is the cause.)

BoringSSL

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.
