Integer Overflow Offensive, First Act: rintersect, hitscan, neartag.

It's time to replace some int32s with 64-bit ints in core engine functions.
The problem is that for example, the dot product is taken between vectors that
may be the difference between two arbitrary points in a sector, so even if one
sticks to the "no blue walls" rule, that doesn't guarantee freedom from
overflows.

Mapster32: fix a div by zero when drawing tile info for void tile in 3D mode.

This was exposed by Clang with -ftrapv, which apparently also traps those.

build/Makefile: Always compile a-c.o with -O2 and without -fcatch-undefined-behavior

This is to not slow down the core drawing functions too much in debugging builds
and mimics the way things are on x86.
