Finished the PDP-10 Move Magnitude opcodes, along with the Push Down and Pop Up opcodes (uncovering some SIMH weirdness along the way)

Added the PDP-10's four arithmetic flags along with a negate() function -- the first of our functions that actually needs to set those flags

Fixed the accumulator update logic in all the PDP-10 half-word self-mode instructions, and started work on EXCH, BLT, and MOVE instructions (the BLT is a real odd-ball, and SIMH does some very strange things with the accumulator used by BLT, which we do NOT attempt to replicate; the strangeness is most noticeable when the accumulator is part of the range being transferred)

Implemented all four primary half-word moves (HLL, HLR, HRL, HRR) but none of the flavors (Z, O, E); need to test the primary instructions first
