Chris Lattner 79a993ea0d Add a disgusting hack to work around a libstdc++ issue. This code should
be removed when PR400 is resolved.

Chris Lattner fc61de3902 Significantly rework linker support for global variables, allowing it to
correctly link globals whose LLVM types do not match.

This fixes several of the F2C SPEC FP benchmarks, which were failing this
due to the implementation of common blocks used by f2c.

Reid Spencer f78508b25e PR466:
* Make the linker find lib*.bca files now instead of lib*.bc since those
  are what the makefiles now generate for bytecode archives.
* Make sure the linker only links archives when LinkLibraries is called.
  Previously if it found a lib*.bc file and that file was a bytecode file,
  it would link in the entire bytecode. This could make -lc -lc fail with
  duplicate symbols error but it shouldn't as searching multiple libraries,
  even the same one more than once, is permitted.
* Now that the above problems are corrected, implement the dependent libs
  feature. After the module is linked with all specified libraries, the
  LinkLibraries function will obtain the set of dependent libraries from
  the linked modules and attemp to find and link against those libraries.

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.

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.
