involved. So use those for now to make printf etc work.

W. J. van der Laan edf397038a mescc: Add r0-cmp-r1 instruction.
This instruction is used to compare two registers and set the flags
accordingly. In current architectures this is the same as r0-r1, but for
RISCV it will be different.  RISC-V does not have condition flags so
(until a better solution) we are going to emulate them there.

of r0-r1.
