Suppress C4701 on 2661 branch.

p256-x86_64.c can't build in MSVC 2013 in debug mode along because of
ecp_nistz256_points_mul's very awkward calling convention (at least one of
g_scalar/p_scalar must be non-NULL).

MSVC 2015 seems to be okay with it, but this branch doesn't build with 2015 yet
and is currently used by gRPC folks. Later they'll move to a branch that builds
with 2015, so the issue won't be pressing. Though the EC_METHOD mul calling
convention is still a little screwy.

The simplest immediate option is to suppress the warning on this branch. The
warning will be left alive on master (which now requires 2015 anyway), but we
should add release-mode builders.

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.
