Added my own defMap. Only saving values that are not loop invariant. Fixed a couple of assertions that were triggered due to registers not being allocated. These both had to do with PHINodes.

You can't have implicit defs that overlap explicit defs, or implicit
defs that alias one another.

by splicing function bodies from the src module to the destination module.

This speeds up linking quite a bit, e.g. gccld time on 176.gcc from 26s -> 20s
when forming the .rbc file, with a profile build.  One of the really strange
but cool effects of this patch is that it speeds up the optimizers as well,
from 12s -> 10.7s, presumably because of better locality???

In any case, this is just a first step.  We can trivially get rid of the
LocalMap now and do other simplifications.
