JIT does not work on MinGW (Windows) builds

[asumagic]

Causes a segfault early.

Doesn't seem to crash anymore but:

• formatFloat calls are suspiciously extremely slow.
• It fails to load "world.png" because a script appears to select a corrupt string.

The former appears to be related to BlindMindStudios/AngelScript-JIT-Compiler#17. Forcing the generic calling convention for formatting functions fixes the issue. A corrupted parameter causes an abnormally big string to be instantiated, resulting in significant slowdowns. I can't see a reason why in particular, this is the 4th parameter and should be stored in a register, so I doubt it's about a forgotten detail of the calling convention. Maybe it has to do with the string reference being passed as the 2nd parameter?

The latter appears to be a corruption issue of the 4th parameter of CMap::CreateTileMap, which takes in the path to the world texture. This could be due to stack corruption of some sort, as that parameter would be in reality the 5th (due to the implicit this pointer passed in RCX), which in the MS x64 convention is the first one that gets pushed to the stack.
So -- it might be that it either is written incorrectly to the stack or something. Find a repro?

Will be fixed in 3338-v12 (probably)
