Chris Lattner ca4ca5520b 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.

Chris Lattner 88c8a23891 Reimplementation of the X86 pattern isel. This is still missing many large

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.
