The ``TargetRegisterInfo`` class is used to describe the register file of the
target and any interactions between the registers.
-Registers in the code generator are represented in the code generator by
-unsigned integers. Physical registers (those that actually exist in the target
-description) are unique small numbers, and virtual registers are generally
-large. Note that register ``#0`` is reserved as a flag value.

Each register in the processor description has an associated
``TargetRegisterDesc`` entry, which provides a textual name for the register
