Re: patch to add AES intrinsics to gcc

I have a patch that I intend to commit before the 10.0 code slush that removes GCC and libstdc++ from the default build on platforms where clang is the system compiler.  We definitely don't want to be supporting our 6-year-old versions of these for the lifetime of the 10.x branch.
