* Improve comments/documentation substantially
...
* Eliminate the releaseMemory method, this is not an analysis
* Change the fixed, active, and inactive lists of intervals to maintain an
iterator for the current position in the interval. This allows us to do
constant time increments of the iterator instead of having to do a binary
search to find our liverange in our liveinterval all of the time, which
substantially speeds up cases where LiveIntervals have many LiveRanges
- which is very common for physical registers. On targets with many
physregs, this can make a noticable difference.
With a release build of LLC for PPC, this halves the time in
processInactiveIntervals and processActiveIntervals, from 1.5s to .75s.
This also lays the ground for more to come.

Fix some things for Mac OSX archives:
...
* ensure trailing spaces are eliminated so they don't factor into the
length of a member's name.
* make sure all the bytes of a name are written even if the name ends in
multiple null characters (bug in OSX ar)
* make sure we provide the full member name when searching for symbols so
the module name is not accidentally duplicated.

Take advantage of the fact that we are allowed to clobber the input module
...
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.
