- Add space for kernel floating point registers to the pcb. These will be

  used to support block copy and zero operations in the kernel which use the
  floating point registers.
- While I'm changing the size, improve the layout of struct pcb, sort by size,
  then alphabetical etc.
- Add some assertions to validate assumptions made about how the pcb is
  allocated.
