2c398fc8f6 Allow the selection-dag based selector to be diabled with -disable-pattern-isel. 
For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.

216198574d Reimplementation of the X86 pattern isel. This is still missing many large 
pieces, but can already do amazing things in some cases.

141c4ec759 1. Make sure that "dot" can be found in the path 
2. Fix a bug where the lib directory specified also had to be cwd
3. Weight the output so archive->archive edges are shorter
4. Generate two different graphs: one for libraries, one for objects.
5. Adjust the properties of the graphs till it looks nice.

6d651234d6 1. If a double FP constant must be put into a constant pool, but it can be 
precisely represented as a float, put it into the constant pool as a
   float.
2. Use the cbw/cwd/cdq instructions instead of an explicit SAR for signed
   division.
