nir: Add a couple quick-and-dirty out-of-SSA helpers
These are designed for use within an optimization pass when SSA becomes
more pain than it's worth. They're very naive and don't generate
anything close to optimal register-based NIR. Also, they may result in
shaders which do not validate because of, for instance, registers in phi
sources. However, the register-based into-SSA pass should be pretty
efficient at cleaning up the mess.
