Only do stuff for the REAL number of physical registers we have, not 1024.

This speeds up live variables a lot, from .60/.39s -> .47/.26s in LLC, for
the first/second pass respectively.

Change the PhysRegsUsed map into a dense array. Seeing that this is a mapping
...
from physical registers, and they are always dense, it makes sense to not have
a ton of RBtree overhead. This change speeds up regalloclocal about ~30% on
253.perlbmk, from .35s -> .27s in the JIT (in LLC, it goes from .74 -> .55).
Now live variable analysis is the slowest codegen pass. Of course it doesn't
help that we have to run it twice, because regalloclocal doesn't update it,
but even if it did it would be the slowest pass (now it's just the 2x slowest
pass :(

Two problems with these lines of code:
...
1. The "work" was not in the assert, so it was punishing the optimized release
2. getNamedFunction is _very_ expensive in large programs. It is not designed
to be used like this, and was taking 7% of the execution time of the code
generator on perlbmk.
Since the assert "can never fail", I'm just killing it.

DSGraphs while they are forwarding. When the last reference to the forwarding
