Missing BURS rule?

Description

The attached patch is a snapshot of my Sapphire work based off 3.1.1. It complies cleanly (working is a whole different problem...) but when I apply a simple clean up to the mutator write barrier code (attached) it seems to break the Opt compiler.

Compiling with the following: $ant -Dhost.name=ia32-osx -Dconfig.name=ExtremeAssertionsOptAdaptiveSapphire
Gives the following (partial) output:
