Quick compiler: debugging assists
A few minor assists to ease A/B debugging in the Quick
compiler:
1. To save time, the assemblers for some targets only
update the object code offsets on instructions involved with
pc-relative fixups. We add code to fix up all offsets when
doing a verbose codegen listing.
2. Temp registers are normally allocated in a round-robin
fashion. When disabling liveness tracking, we now reset the
round-robin pool to 0 on each instruction boundary. This makes
it easier to spot real codegen differences.
3. Self-register copies were previously emitted, but
marked as nops. Minor change to avoid generating them in the
first place and reduce clutter.
