    include: Implement some inline functions in C instead of assembly.

    This way the same code can be used on all platforms.

Tested in a clean 32-bit WINEPREFIX.

Thread/issue reference(s) for other users able to reproduce this issue:

* https://github.com/Winetricks/winetricks/issues/1280
* https://forum.winehq.org/viewtopic.php?f=8&t=30883&p=123789#p123789

Both these users are on Arch Linux...
I'm on Gentoo and using gcc 9.1.0...

So perhaps  gcc-9.1.0 is "optimising" these C blocks?
I'll test building Wine 4.12.1 with -O0 instead of -O2 ...
