Tom Tromey 3d567982ac implement support for "enum class"
This adds support for the C++11 "enum class" feature.  This is
PR c++/15246.

I chose to use the existing TYPE_DECLARED_CLASS rather than introduce
a new type code.  This seemed both simple and clear to me.

I made overloading support for the new enum types strict.  This is how
it works in C++; and it didn't seem like an undue burden to keep this,
particularly because enum constants are printed symbolically by gdb.

Built and regtested on x86-64 Fedora 20.
