Timm Bäder 1ecaa617e7 [clang][Interp] Handle enums 
Handle DeclRefExprs of enum types. They are otherwise handled like
integers.

Timm Bäder f444a7cc16 Revert "[clang][Interp] Handle enums" 
This reverts commit c090295916.

One of the test cases fails. Revert this until I know a way to make it
work reliably.

Timm Bäder df1cc801da [clang][Interp] Record item types in InterpStack 
The type information is lost when pushing things on the stack. When
later pop()ing items of the wrong type, we can instead simply get
garbage values and those problems are hard to find. Add another stack to
record the type of item we pushed and use that for debugging.

Timm Bäder aa7c5c9c4e [clang][Interp] Handle missing local initializers better 
This is illegal in a constexpr context. We can already figure that out,
but we'd still run into an assertion later on when trying to visit the
missing initializer or run the invalid function.

Owen Pan 7cd441ff53 [clang][NFC] Wrap TYPE_SWITCH in "do while (0)" in the interpreter 
Wraps the expansions of TYPE_SWITCH and COMPOSITE_TYPE_SWITCH in
the constexpr interpreter with "do { ... } while (0)" so that these
macros can be used like this:

if (llvm::Optional<PrimType> T = Ctx.classify(FieldTy))
  TYPE_SWITCH(*T, Ok &= ReturnValue<T>(FP.deref<T>(), Value));
else
  Ok &= Composite(FieldTy, FP, Value);

This bug was found while testing D116316. See also review comment:
https://reviews.llvm.org/D64146?id=208520#inline-584131

Also cleaned up the macro definitions by removing the superfluous
do-while statements and removed the unused INT_TPYE_SWITCH macro.
