Summary: [mc] Try and reenable the inst to data lowering
optimization
Product: libraries
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: Common Code Generator Code

The Inst to Data lowering was causing reads after free since we deleted the old
inst fragment, but symbols would still point to it.
It has been disable for now, but it could be reenabled if each fragment knew
its symbols. That way we would be able to move the symbols to the new fragment.
We would also be able to do this during layout instead of after it.
Yet another way to do it is make sure that symbols never point to instruction
fragments by creating dummy data fragments when necessary.
