A class that can track all registers with locations in a UnwindRow object.
Register locations use a map where the key is the register number and the the value is a UnwindLocation.
The register maps are put into a class so that all register locations can be copied when parsing the unwind opcodes DW_CFA_remember_state and DW_CFA_restore_state.
