Richard Smith 1106d967df Add support for enum comparisons and bitwise operators (#7356) 
If C++ overload resolution selects a builtin operator candidate for an
enum comparison or bitwise operator, provide support for that operator
by generating a corresponding Carbon builtin function. This is
structured to be easily extensible to other C++ builtin overload
candidates if we so choose, but for now the operators defined in the
prelude are doing what we want in most cases.

Bitwise operators on enums produce the same enum type as a result. This
intentionally deviates from C++, where they produce a promoted integral
type.
