Message:

Improve native call performance

Reviewed by Gavin Barraclough.

Fix the windows build by adding calling convention declarations everywhere,
chose fastcall as that seemed most sensible given we were having to declare
the convention explicitly. In addition switched to fastcall on mac in the
deluded belief that documented fastcall behavior on windows would match
actual its actual behavior.
