Put the invalid flag of OwningResult into the Action pointer.
This shrinks OwningResult by one pointer. Since it is no longer larger than OwningPtr, merge the two.
This leads to simpler client code and speeds up my benchmark by 2.7%.
For some reason, this exposes a previously hidden bug, causing a regression in SemaCXX/condition.cpp.

Unify the code for defining tags in C and C++, so that we always
introduce a Scope for the body of a tag. This reduces the number of
semantic differences between C and C++ structs and unions, and will
help with other features (e.g., anonymous unions) in C. Some important
points:

- Fields are now in the "member" namespace (IDNS_Member), to keep
them separate from tags and ordinary names in C. See the new test
in Sema/member-reference.c for an example of why this matters. In
C++, ordinary and member name lookup will find members in both the
ordinary and member namespace, so the difference between
IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but
only in C++!).
- We always introduce a Scope and push a DeclContext when we're
defining a tag, in both C and C++. Previously, we had different
actions and different Scope/CurContext behavior for enums, C
structs/unions, and C++ structs/unions/classes. Now, it's one pair
of actions. (Yay!)

There's still some fuzziness in the handling of struct/union/enum
definitions within other struct/union/enum definitions in C. We'll
need to do some more cleanup to eliminate some reliance on CurContext
before we can solve this issue for real. What we want is for something
like this:

struct X {
struct T { int x; } t;
};

to introduce T into translation unit scope (placing it at the
appropriate point in the IdentifierResolver chain, too), but it should
still have struct X as its lexical declaration
context. PushOnScopeChains isn't smart enough to do that yet, though,
so there's a FIXME test in nested-redef.c
