d975a01709 ZDBSP fix: ShoveSegBehind needs to check for a positive result from Heuristic, not non-zero.

c51e49f02f For ZDBSP:
- 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.

6a1a0e007a - Added runtime detection of SSE2 so that ZDBSP can select either the regular
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.

1a979de350 ZDBSP fixes:
- AddIntersection() should convert to doubles before subtracting the vertex
  from the node, not after, to avoid integer overflow. (See cah.wad, MAP12
  and MAP13.) A simpler dot product will also suffice for distance calculation.
- Splitters that come too close to a vertex should be avoided. (See cata.wad.)
- Red-Black Tree implementation was broken and colored every node red.
- Moved most of the code for outputting degenerate GL subsectors into another
  function.
- Removed forgotten debugging file dump from WriteSSectors2().
- Enabled reference optimization and COMDAT folding in the linker for a slightly
  smaller executable.

3128c11fd1 ZDBSP fixes:
- 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.
