b6661b480b Improved shuffle normalization to avoid using extract/build when we 
can extract using different indexes for two vectors. Added a few tests
for vector shuffles.

f9dd858359 simplify the conditions on two gigantic if's, decreasing indentation

6afddeeed1 factor a bunch of copy/paste code out into a helper function. 
Eliminate the cases checking for cond?0:-1, since that is already
handled by commutative checking.

1cddd8346f Don't brute-force analyze cubic or higher polynomials. 
If this patch causes a performance regression for anyone, please let me know,
and it can be fixed in a different way with much more effort.

42942c0bc5 Adds extern "C" ints to the .cpp files that use RegisterTarget, as 
well as 2 files that use "Registrator"s. These are to be used by the
MSVC builds, as the Win32 linker does not include libs that are
otherwise unreferenced, even if global constructors in the lib have
side-effects.

Patch by Scott Graham!

52ce276405 When splitting a SHUFFLE_VECTOR, try to have the result 
use SHUFFLE_VECTOR instead.  If not practical, fall back
to the old scheme of building the split result by hand
using a BUILD_VECTOR.

521cee6a9c Add support for building a ScheduleDAG from MachineInstrs. This is currently 
fairly conservative; it doesn't do alias-analysis queries and it doesn't
attempt to break anti-dependencies.

0a3ae5c0f2 Remove the FlaggedNodes member from SUnit. Instead of requiring each SUnit 
to carry a SmallVector of flagged nodes, just calculate the flagged nodes
dynamically when they are needed.

The local-liveness change is due to a trivial scheduling change where
the scheduler arbitrary decision differently.

9dc2bd7973 Modify the intrinsics pattern to separate out the "return" types from the 
"parameter" types. An intrinsic can now return a multiple return values like
this:

  def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty],
                                    [LLVMMatchType<0>, LLVMMatchType<0>]>;
