When the normalizeSpillWeights function was introduced, I forgot to remove this
normalization.

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

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.

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.

When LLVM_TARGETS_TO_BUILD didn't include all the targets, the

This adds the most basic operations on v2i32: passing parameters,

Start cleaning up MergeFunctions to look more like the rest of LLVM. The
primary change here is to move the methods responsible for comparison into the
new FunctionComparator object. Some comments added. There's more to do.
