[RFC] libressl: add assembly for aarch64, ppc*, extra assembly for arm
This yields significant speedups (20x) in some things (AES/ghash) on platforms with hardware crypto support (e.g. POWER8 and newer, and most aarch64) as well as enhances performance of assorted alogrithms by using optimized assembly implementations instead of portable fallbacks. E.g. on aarch64 https://gist.githubusercontent.com/q66/c75a46fc7d0c27eff21cc9d70639bf95/raw/dde1f60e304ef8f4a4049d41388d9c25e63b4a1e/gistfile1.txt

As it is now, libressl only supports asm for x86(_64) and to a limited degree, 32-bit ARM. The extra support was added by my project: https://github.com/q66/libressl-portable-asm

Everything was tested, test suite passes on all platforms, and benchmarks were run on relevant hardware, confirming the speedups.

I still think we should move back to OpenSSL, since there are many reasons to do so (even disregarding performance) and the performance is still better on it (as there are various algos that don't have optimized implementations under libressl at all) but this could be a decent stopgap solution, enabling at least basic things (like hardware AES on non-x86 systems).

More testing (mainly benchmarking, test suite is known to pass universally) on ~~armv7 and~~ aarch64 is still pending.
