Eidolon 6648e55972 Prevent overflow when scaling textures 
Fixes KartKrew/Kart#844 which is caused by scaling the texheight by a
spryscale that is too large, triggering arithmetic overflow before the
overflow check even occurs. This is a performance hit, but should not be
very intense with release optimizations.

Instead, we use saturating arithmetic using the same integer promotion
technique as before, but checking in both directions, and also checking
for the multiplication before the addition.

There is an optimization opportunity here and anywhere that overflow
checks are used, by using compiler intrinsics which check the overflow
flag bit on the CPU instead of using integer promotion.
