Add support for the compilation of the is_map/1 guard to native code
Namely, extend the HiPE tagging scheme info, properly handle the translation of the (is_)map type test to Icode and RTL and support handling of the map() type in the type system. While at it, also performed some clean up of things that needed small fixes.
