History
Jakob Stoklund Olesen d9e5c764bf Freeze reserved registers before starting register allocation. 
The register allocators don't currently support adding reserved
registers while they are running.  Extend the MRI API to keep track of
the set of reserved registers when register allocation started.

Target hooks like hasFP() and needsStackRealignment() can look at this
set to avoid reserving more registers during register allocation.
