A register file descriptor.
This struct allows to describe processor register files. In particular, it helps describing the size of the register file, as well as the cost of allocating a register file at register renaming stage. FIXME: this struct can be extended to provide information about the number of read/write ports to the register file. A value of zero for field 'NumPhysRegs' means: this register file has an unbounded number of physical registers.
