c8b6926801 Added legal stuff, fixed some formatting issues. Removed the graph generator stuff as it was only meant for debugging the solver.

44233430ea Add the testcase from PR 4668. This works at the 
moment, but it's a fragile area.

66ecec971d New C++ PBQP solver. Currently about as fast (read _slow_) as the old C based solver, but I'll be working to improve that. The PBQP allocator has been updated to use the new solver.

2d90fbe8be Fix several fixmes and clean up code by sinking *all* section 
creation activity into the target-specific subclasses of TLOF.
Before this, globals with explicit sections could be created by
the base class.

1. make getOrCreateSection protected, add a new getExplicitSectionGlobal
   pure virtual method to assign sections to globals with a specified
   section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is
   now just a static method for ELF.
4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16.
   They are now all detangled and understandable, woo! :)

668a0ff5ef Fix a bug in x86's PreprocessForRMW logic that was exposed 
by aggressive chain operand optimization. UpdateNodeOperands
does not modify the node in place if it would result in
a node identical to an existing node.

01b8a3593b Fix a few places in DAGCombiner that were creating all-ones-bits 
and high-bits values in ways that weren't correct for integer
types wider than 64 bits. This fixes a miscompile in
PPMacroExpansion.cpp in clang on x86-64.

6ee52e0047 Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.

6e4065d7c6 When using NEON for single-precision FP, the NEON result must be placed in D0-D15 as these are the only D registers with S subregs. Introduce a new regclass to represent D0-D15 and use it in the NEON single-precision FP patterns.
