The implementation might be better to have a method is64Bit() in the class
SymbolicFile instead of having the static routine isSymbolList64Bit() in
llvm-nm.cpp . But this is very much in the sprit of isObject() and
getNMTypeChar() in llvm-nm.cpp that has a series of if else statements
based on the specific class of the SymbolicFile. I can update this if
folks would like.
Also the tests were updated to be explicit about checking the address for
64-bits or 32-bits from object files.
