- Fixed the OrgSectorMap generation in FLevel::RemoveExtraSectors().
- Added a version of ClassifyLine compiled with SSE (but not SSE2) optimization
for people with Pentium 3/Athlon XPs to use.
- Added ClassifyLine backpatching for the GCC Windows build. The first time a
function calls ClassifyLine, it has to check which version to use and jump
to the appropriate one. After that, it calls the desired one straight away.

ClassifyLine routine or a version compiled with SSE2 optimizations. This
pretty much removes any reason to do a separate SSE2 build, since most of
the time is spent in ClassifyLine, so using SSE2 in just that one function
helps the most.

the runtime is spent in that function. I should probably write a faster
vertex finding routine, since I currently just do a linear search through
all the vertices. That ought to help speed up SplitSegs, the second most
time-consuming routine. I also tried storing vertices as doubles instead
of fixeds, but that made performance drop across the board, so that's a
change that didn't make it in.
Ironically, the GCC compiled version is noticeably faster than the VC
version for x87 math, but VC produces a marginally faster SSE2 version.

- MapSideDef.sector was declared signed but treated as unsigned.
- Degenerate (one-dimensional) subsectors could throw away segs when
output for GL nodes depending on the seg ordering.
