505c6fac89 Change the RAGreedy register assignment order so large live ranges are allocated first. 
This is based on the observation that long live ranges are more difficult to
allocate, so there is a better chance of solving the puzzle by handling the big
pieces first. The allocator will evict and split long alive ranges when they get
in the way.

RABasic is still using spill weights for its priority queue, so the interface to
the queue has been virtualized.

0c9c9c5beb Fix C++0x incompatibility. The signature of std::make_pair<> changes from: 
template <class T1, class T2> pair<T1,T2> make_pair(const T1&, const T2&);
to
  template <class T1, class T2> pair<V1, V2> make_pair(T1&&, T2&&);
so explicitly specifying the template arguments to make_pair<> is going to break
when C++0x rolls through. Replace them with equivalent std::pair<>. Patch by
James Dennett!

clang uses DBuilder, so it requries corresponding change.

bde7e8b3e0 MachineConstantPoolValues are not uniqued, so they need to be freed if they 
share entries. Add a DenseSet to MachineConstantPool for the MachineCPVs that
it owns.

This will hopefully fix the MC/ARM/elf-reloc-01.ll failure on the leaks bots.

It seems it affected configuration --target=i686-pc-mingw32, I don't know and will investigate why.
