Preserve exceptions information during calls code generation.

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.
