Owen Anderson 6773d388aa Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

Gabor Greif e16561cd5d Here is the bulk of the sanitizing. 
Almost all occurrences of "bytecode" in the sources have been eliminated.

Reid Spencer 8d4ff90680 If an archive is not recognized as an LLVM bytecode archive then declare 
that it is native so that the linker will pass it on downstream. This avoids
a problem where the native link line fails because there is both a .so and
a .a file. The .a file gets processed as bytecode and then dropped from the
command line.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Anton Korobeynikov d61d39ec53 Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

Reid Spencer 546436c482 Finish removal of EH usage from the Archive library. The REQUIRES_EH flag 
in lib/Bytecode/Archive/Makefile is now removed. One small step closer to
a smaller LLVM.

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Reid Spencer fe73bfcfdb For PR351: \ 
* Convert functions to Linker:: methods. \
* Remove unneeded #includes \
* Utilize sys::Path utilities not FileSupport utilities \
* Move File & Library linking functions to other source files

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.
