(Which is fine BTW, since the majority usage is "T* x" not "T *x"; https://wiki.openjdk.java.net/display/HotSpot/StyleGuide points out we do such adjustments.)

Are there any other places where C2 uses normal IR to access the mark word of an object, and if so, is a similar bug fix needed there?  If so, the tricky logic for building the free-standing LoadXNode needs to be factored into a subroutine.
