[#RVM-355] Complete SPEC JVM with 20 iterations dies in GC - jira.codehaus.org

I think since ~r13904 there is a repeatable failure when run the complete SPEC JVM is run with -m20 -M20 as shown here:

The change was an opt compiler change (to remove unreachable code) but it seems to have exposed a GC bug.

This issue relates to:
RVM-352	Running many iterations of _200_check fails floating point remainder test

This issue is depended upon by:
RVM-42	Build/Test infrastructiure to compute compiler DNA

More recent results (r13907) without expression folding suggest that this is a bug somewhere outside of expression folding:

At least needs investigation before we can make release.

Running a full Spec JVM for 20 iterations since closing ~~RVM-352~~ now completes.
