New Revision: 110119

URL: http://llvm.org/viewvc/llvm-project?rev=110119&view=rev
Log:
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.
