aee38ea569 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.

be0b356593 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.

4bbfbff119 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.

5a837defff FindGlobalNamed used to take 2.92s out of 8.39s running a profile build of 
gccld -disable-opt on 252.eon.

This patch deletes it and replaces it with a map.  The proper fix for this
is to fix PR411, but this will do in the short term.

gccld on eon now takes 5.51s, which is 50% faster than before this patch. :)

fe41069070 Concisify some code 
Do not call FindGlobalNamed when we know we will ignore the result (because
we are not going to link a static symbol anyway).  This speeds up
gccld -disable-opt on 252.eon from 8.63s to 8.39s.

1715ce00e4 Modified the linker so that it always links in an object from an archive 
that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.

ee8adb1955 This version of Linker.cpp works a lot better, but it's a little messy. Sorry. 
Use FileOpenable() instead of FileExists().
Create IsBytecode() predicate -- like IsArchive(), but for bytecode files.
Use IsBytecode() before trying to load any file as a bytecode file.

3b3640a373 Shorten and correct some function-header comments. 
Make "verbose" output MUCH nicer. Now it tells you when you are linking a
bytecode file, or an archive, and whether it's because you called it by name,
or because you gave it a -l option, and it says "Trying" before it takes
action and prints a message in the past tense afterwards.

Make LinkFiles not skip the first file in Files.

Make LinkFiles warn you if it can't find a file and LLVM_LIB_SEARCH_PATH is
unset.

700867bb69 Checking in Chris's suggestions: 
Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
the symbol table and invalidate the value of the iterator.
Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.
