First pass at implementing C++ enum semantics: calculate (and store) an
"integer promotion" type associated with an enum decl, and use this type to
determine which type to promote to. This type obeys C++ [conv.prom]p2 and
is therefore generally signed unless the range of the enumerators forces
it to be unsigned.
Kills off a lot of false positives from -Wsign-compare in C++, addressing
