Owen Anderson 8d9e92ce2d Weight loop unrolling counts by nesting depth. Unrolling deeply nested loops tends to cause high ...

register pressure and thus excess spills, which we don't currently recover from well.  This should
be re-evaluated in the future if our ability to generate good spills/splits improves.

Partial fix for <rdar://problem/7635585>.
