Reid Spencer 8bb258d1ea Implement dependent library linking. It is no longer required that -lstdc++ 
-lstdsup++ no -lc be passed on the command line to llvm linkers if the
progam being linked was compiled with the C/C++ Front End or Stacker.

Reid Spencer c2455ca7b7 Reduce the amount of work in LinkInArchive by not searching the archive for 
symbols it has already identified as not defining.

Chris Lattner 7391dde138 Simplify the remapper by only needing one map, since the body of the functions 
being linked do not need to be remapped any longer.

Chris Lattner 2f0557d0e4 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.
