More work on ScalarExprEmitter::EmitCastExpr: for every cast kind, either
...
implement it explicitly or assert that it doesn't make sense for a scalar.
This caught a couple interesting issues: one, CK_BaseToDerivedMemberPointer
casts were getting silently miscompiled, and two, Sema was constructing some
strange implicit casts of type CK_UserDefinedConversion.
The change in SemaExprCXX makes sure the cast kinds are getting set correctly.

Use the more general Evaluate infrastructure for folding constant DeclRefs
...
instead of checking explicitly for an EnumConstantDecl. This folds references
to constant integer VarDecls, which has two benefits:
1. Slightly smaller emitted code from emitting a constant instead of a load,
and skipping emitting some constant globals.
2. Some code forgets to define static constant member variables; emitting a
load instead of the value in that case leads to a link error. (Such programs
are technically not well-formed, but in practice build with g++.)
