Demote check for bison from error to warning and make sure that the
makefile can handle an empty definition for BISON variable.

and a handler, which would produce errors like:
  terminate called after throwing an instance of 'std::string'
we must comment out setting -fno-exceptions until PR797 is completely
fixed. Once libraries like lib/System and lib/Support are exception free,
we can turn it back on.

1. Actually turn on -fno-exceptions in libraries that do not have the
   REQUIRES_EH option in their Makefile. The following library file size
   savings were made (DEBUG):
      libLLVMDataStructure.a  525K
      libLLVMCore.a           380K
      libLLVMCodeGen.a        350K
      libLLVMTransformUtils.a 305K
      libLLVMScalarOpts.a     270K
      libLLVMAnalysis.a       247K
      libLLVMSelectionDAG.a   233K
      libLLVMipo.a            175K
      LLVMX86.o               123K
      LLVMPPC.o                81K
      libLLVMipa.a             17K
                 TOTAL      2,706K
      Note that the savings is actually a little larger than this because
      I didn't count any of the libraries that had small changes.

2. Remove REQUIRES_EH from the AsmParser library as it is now exception
   free. This resulted in a nearly 78K drop in the size of the debug
   library for AsmParser.

1. Change the usage of LOADABLE_MODULE so that it implies all the things
   necessary to make a loadable module. This reduces the user's burdern to
   get a loadable module correctly built.
2. Document the usage of LOADABLE_MODULE in the MakefileGuide
3. Adjust the makefile for lib/Transforms/Hello to use the new specification
   for building loadable modules
4. Adjust the sample project to not attempt to build a shared library for
   its little library. This was just wasteful and not instructive at all.

Turn -pedantic and -Wno-long-long compile flags on by default. In a few
places, avoid the warnings by removing these options in the local makefile.
One notable exception: lib/Target/CBackend/Writer.cpp. These warnings are
left on as a reminder to developers to clean them up.

1. Remove the LLVM_DO_NOT_BUILD feature (not needed any more)
2. Ensure that lib/VMCore gets built first. This needs to be done because
   VMCore now uses tblgen to generate the Intrinsics header which are
   needed in other libraries. In parallel builds, this can cause problems.

1. Don't force debug builds to have assertion checking turned on always.
   Let the default (on) be taken, or overridden by the command line
2. Create two new BuildModes based on assertion checking: Release+Assert
   and Debug-Assert.
3. Ensure that when building a distribution we get a release build with
   assertions enabled, regardless of the tree's configuration.
4. (unrelated) Fix library name generation for llvm-config usage.
