Apple's AArch64 ABI deviates from the standard in a few places:
https://developer.apple.com/library/archive/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html
This is covered by the two first patches.

Also, macOS/x86 (32-bit) requires the first argument to be aligned on a 16 byte boundary, which is covered by the third patch. I didn't put this behind an ifdef as I figured it wouldn't hurt to do it on the other OSes; but no strong opinion either way.

Background: I just integrated TinyCC in Frida:
https://frida.re/news/2019/09/18/frida-12-7-released/
I also added a few additional APIs that I'm not sure if will be of interest to upstream, but figured it would be best to start with the fixes.

Thank you so much for this awesome software!
