Log message:

For PR797: http://llvm.org/PR797 :
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.
