always zero in this context" warning logic. Also, make the diagnostic
itself more precise when referring to pointer values ("NULL" vs. "zero").

(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.
Note to self: stop baiting Doug in my commit messages.

migrate work in the destructors of PathDiagnosticClients from their
destructors to FlushReports(). The destructors now currently call
FlushReports(); this will be fixed in a subsequent patch.

This is conceptually correct, but adds a huge hack to HighlightMacros which is
in fact doing all sorts of mutation to the Preprocessor. See FIXME.
Chris, please review.

a little fuzzy, but conceptually it's just uniquing the identifier.
Chris, please review. I debated splitting into const/non-const versions where
the const one propogated constness to the resulting IdentifierInfo*.

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.

an "assign expression", representing the expressions where the value
binding occurs and the assignment takes place respectively. These are
largely syntactic clues for better error reporting.

type of the object even when it is dependent. Specifically, this makes
sure that we get the right type for "this->", which is important when
performing name lookup into this scope to determine whether an
identifier or operator-function-id is a template name.

expressions, keep track of whether we are immediately taking the
address of the expression. Pass this flag when building a declaration
name expression so that we handle pointer-to-member constants
properly.
