This patch changes the generation of CGFunctionInfo to contain the FunctionProtoType if it is available. This enables the code generation for call instructions to look into this type for exception information and therefore generate better quality IR - it will not create invoke instructions for functions that are know not to throw. llvm-svn: 253926
