SVREMAP merge into SVSTATE now done, was quite intrusive:
involved replacing a low-level class in the simulator which is used
by every single SVP64 unit test.
the next step is to make the svremap instruction "persistent" so that
it does not have to be repeated 6 times. that brings instruction
count down from 15 to 9.
