2045c47aff - Add sugregister logic to handle f64=(f32,f32). 
- Support mips1 like load/store of doubles:

Instead of:
  sdc $f0, X($3)
Generate:
  swc $f0, X($3)
  swc $f1, X+4($3)

835ca07991 Added a new Spiller implementation which wraps LiveIntervals::addIntervalsForSpills. 
All spiller calls in RegAllocLinearScan now go through the new Spiller interface.
The "-new-spill-framework" command line option has been removed. To use the trivial in-place spiller you should now pass "-spiller=trivial -rewriter=trivial".
(Note the trivial spiller/rewriter are only meant to serve as examples of the new in-place modification work. Enabling them will yield terrible, though hopefully functional, code).

fd96b13a94 Add TOOLALIAS makefile variable; this defines an alternate name for a program 
which the makefiles will create by symlinking the actual tool to.
 - For use by clang, where we want to make 'clang++' and alias for clang (which
   enables C++ support in the driver)

 - Not sure this is the best approach, alternative suggestions welcome!

0257dd375d Don't require LiveVariables for PHIElimination. Enable critical edge splitting 
when LiveVariables is available.

The -split-phi-edges is now gone, and so is the hack to disable it when using
the local register allocator. The PHIElimination pass no longer has
LiveVariables as a prerequisite - that is what broke the local allocator.
Instead we do critical edge splitting when possible - that is when
LiveVariables is available.

834b08af8d Add a target hook to allow changing the tail duplication limit based on the 
contents of the block to be duplicated.  Use this for ARM Cortex A8/9 to
be more aggressive tail duplicating indirect branches, since it makes it
much more likely that they will be predicted in the branch target buffer.
Testcase coming soon.

5eea342673 The llvm-gcc front-end and the pass manager use two separate TargetData objects. 
This is probably not confined to *just* these two things.

Anyway, the llvm-gcc front-end may look up the structure layout information for
an abstract type. That information will be stored into a table with the FE's
TD. Instruction combine can come along and also ask for information on that
abstract type, but for a separate TD (the one associated with the pass manager).

After the type is refined, the old structure layout information in the pass
manager's TD file is out of date. If a new type is allocated in the same space
as the old-unrefined type, then the structure type information in the pass
manager's TD file will be wrong, but won't know it.

Fix this by making the TD's structure type information an abstract type user.
