argument. This avoids the argument from being silenced when the argument is
the NULL macro, which is defined in a system header. This also makes the output
a bit nicer, e.g.:
t.c:8:3: warning: null passed to a callee which requires a non-null argument
func1(NULL, cp2, i1);
^ ~~~~
vs something like:
t.c:8:10: warning: argument is null where non-null is required
func1(NULL, cp2, i1);

expressions. We are now missing template instantiation logic for only
three classes of expressions:
- Blocks-related expressions (BlockExpr, BlockDeclRefExpr)
- C++ default argument expressions
- Objective-C expressions
Additionally, our handling of DeclRefExpr is still quite poor, since
it cannot handle references to many kinds of declarations.
As part of this change, converted the TemplateExprInstantiator to use
iteration through all of the expressions via clang/AST/StmtNodes.def,
ensuring that we don't forget to add template instantiation logic for
any new expression node kinds.

expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.
Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.

and objects of this class are derived from 'NSProxy'.
Under such conditions, which means that every method possible is
implemented in the class, we should not issue "Method definition not found"
warnings.

can. Also, delay semantic analysis of initialization for
value-dependent as well as type-dependent expressions, since we can't
always properly type-check a value-dependent expression.

redundant functionality. The result (ASTOwningVector) lives in
clang/Parse/Ownership.h and is used by both the parser and semantic
analysis. No intended functionality change.

llvm::SmallVector that owns all of the AST nodes inside of it. This
RAII class is used to ensure proper destruction of AST nodes when
template instantiation fails.

temporaries are generated for some object-constructing expressions in
templates that are not type-dependent.
Also, be sure to introduce the variable from a CXXConditionDeclExpr
into the set of instantiated local variables.

describe the construction of a value of a given type using function
syntax, e.g.,
T(a1, a2, ..., aN)
when the type or any of its arguments are type-dependent. In this
case, we don't know what kind of type-construction this will be: it
might construct a temporary of type 'T' (which might be a class or
non-class type) or might perform a conversion to type 'T'. Also,
implement printing of and template instantiation for this new
expression type. Due to the change in Sema::ActOnCXXTypeConstructExpr,
our existing tests cover template instantiation of this new expression
node.

statement was using an rvalue reference during the template
definition. However, template instantiations based on an lvalue
reference type are well-formed, so we delay checking of these property
until template instantiation time.
