c5598c7531 Export TARGET_TRIPLE on LLVM.cmake. It is necessary for running tests 
on Clang when it builds using LLVM as an external library.

Fixes PR9293.

e1308394f1 Fixed a bug in the enhanced disassembler that caused 
it to ignore valid uses of FS and GS as additional
base registers in address computations.  Added a test
case for this.

da40bcab44 More fcopysign correctness and performance fix. 
The previous codegen for the slow path (when values are in VFP / NEON
registers) was incorrect if the source is NaN.

The new codegen uses NEON vbsl instruction to copy the sign bit. e.g.
        vmov.i32        d1, #0x80000000
        vbsl    d1, d2, d0
If NEON is not available, it uses integer instructions to copy the sign bit.

17add01160 Keep track of how many times a live range has been dequeued, and prioritize new ranges. 
When a large live range is evicted, it will usually be split when it comes
around again. By deferring evicted live ranges, the splitting happens at a time
when the interference pattern is more realistic. This prevents repeated
splitting and evictions.

58efee5c3e Be more aggressive about evicting interference. 
Use interval sizes instead of spill weights to determine if it is legal to evict
interference. A smaller interval can evict interference if all interfering live
ranges are larger.

Allow multiple interferences to be evicted as along as they are all larger than
the live range being allocated.

Spill weights are still used to select the preferred eviction candidate.

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!

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.
