efb59d28c5 CMake: Change somme target library names: 
XCore->XCoreGen
PIC16->PIC16CodeGen

After updating your working copy, the first build will fail because it
is using the old library dependencies. Start the build again and it
will work fine.

ee99317554 CMake: add version control info to PACKAGE_VERSION, if available. 
Adds "svn" or "git", depending on the VCS used. If svn, adds the
revision number as well.

bae696956b Oops. Don't normalize spill weights twice. 
When the normalizeSpillWeights function was introduced, I forgot to remove this
normalization.

This change could affect register allocation. Hopefully for the better.

0055f97f72 OK, that's it. This test is going away now. But don't worry, I am taking it to a 
nice farm in the country where it can play with other tests. And bunnies.

It is not clear what is being tested, and the revision history shows a bunch of
random changes to the expected instruction count. Clearly, we are just fudging
it to pass whenever it fails.

e5c500b37d Support x86 AVX 256-bit instruction intrinsics. Right now support all of them, but 
as soon as we properly codegen the simple vector operations in clang, remove the
unnecessary builti-ins/intrinsics from clang and llvm.

ab37f50838 Make SCEVUnknown a CallbackVH, so that it can be notified directly 
of Value deletions and RAUWs, instead of relying on ScalarEvolution's
Scalars map being notified, as that's complicated at best, and
insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.

82fe467ca5 Add preliminary v2i32 support for SPU backend. As there are no 
such registers in SPU, this support boils down to "emulating" 
them by duplicating instructions on the general purpose registers. 

This adds the most basic operations on v2i32: passing parameters,
addition, subtraction, multiplication and a few others.
