(without complaining if it fails) to get proper semantics: reference
binding with a derived-to-base conversion and the enumeration of
constructors for user-defined conversions. There are probably more
cases to fix, but my prior attempt at statically ensuring that
complete-type checking always happens failed. Perhaps I'll try again.

With this change, Clang can parse include/llvm/*.h!

DiagnoseSignCompare into Sema::CheckSignCompare and call it from more places.

Add some enumerator tests.  These seem to expose some oddities in the
types we're converting C++ enumerators to;  in particular, they're converting
to unsigned before int, which seems to contradict 4.5 [conv.prom] p2.

If this bothers you, I can add it back in a mode where non-source diagnostics go
to stderr and only source diagnostics use -html-diags, but I don't think anyone
uses this.

still be dependent or invoke an overloaded operator. Previously, we
only supported builtin operators.

BinaryOperator/CompoundAssignOperator didn't have this issue because
we always built a CXXOperatorCallExpr node, even when name lookup
didn't find any functions to save until instantiation time. Now, that
code builds a BinaryOperator or CompoundAssignOperator rather than a
CXXOperatorCallExpr, to save some space.

appears in a deprecated context.  In the new strategy, we emit the warnings
as usual unless we're currently parsing a declaration, where "declaration" is
restricted to mean a decl group or a few special cases in Objective C.  If
we *are* parsing a declaration, we queue up the deprecation warnings until
the declaration has been completely parsed, and then emit them only if the
decl is not deprecated.
We also standardize the bookkeeping for deprecation so as to avoid special cases.
