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.
