Silence ARMv8 deprecated IT instruction warnings. ARMv8 kindly deprecated most of its IT instructions in Thumb mode. These files are taken from upstream and are used on both ARMv7 and ARMv8 processors. Accordingly, silence the warnings by marking the file as targetting ARMv7. In other files, they were accidentally silenced anyway by way of the existing .arch lines. This can be reproduced by building with the new NDK and passing -DCMAKE_ASM_FLAGS=-march=armv8-a. Some of our downstream code ends up passing that to the assembly. Note this change does not attempt to arrange for ARMv8-A/T32 to get code which honors the constraints. It only silences the warnings and continues to give it the same ARMv7-A/Thumb-2 code that backwards compatibility dictates it continue to run.

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.
