Title: Fix ABI on 32-bit non-Windows x86: go back to trampoline size 10

The trampoline size is part of the ABI, so it cannot change. Move the
logic from the stdcall and thiscall trampolines to the functions they
call, to reduce them both to 10 bytes.

This drops the previously added support for raw THISCALL closures on
non-Windows. (Non-raw THISCALL closures still work.)
