This patch enables the PostRA scheduler in the SNB scheduler model.
This model is used by default for 32-bit and 64-bit Linux and
Windows.

We were previously using PostRA by default on 32-bit until I
changed 'pentium4' to use the SNB scheduler earlier this week.

I haven't done any perf measurements with this yet. Anything
specific people would like to see?
