## Message

```
stage2 regalloc: Add freezeRegs/unfreezeRegs API

The freeze/unfreeze API replaces the exceptions API for hopefully
preventing bugs in codegen code using the RegisterManager. The
exceptions API is still available for backwards compatibility and will
be removed once all backends transition to the new freeze/unfreeze
API.

```
