Fix typo, thanks Sebastian!

Simplify.

Some member pointer casting tests.

Add case for CK_DerivedToBaseMemberPointer cast kind to
AggExprEmitter::VisitCastExpr.

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.

Cleanup for ScalarExprEmitter::EmitCastExpr; no functional changes.

Fix for PR5594: use EmitGlobalDefinition instead of EmitCXXDestructor so that
we check whether the vtable needs to be generated.

When adding an implicit destructor, make sure to mark it as virtual if it overrides existing destructors.

Lazily create the __cxa_pure_virtual reference.

Use the new CovariantThunkAdjustment in the vtable builder.

Make the pure virtual methods map a set instead.

Simplify and fix up the handling of implicit constructors, copy assignment
operators, and destructors.  Avoids generating declarations/definitions of
trivial constructors/destructors, and makes sure the trivial copy assignment
operator is generated when necessary.
