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.

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.

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

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.

definition. However, template instantiations based on an lvalue
reference type are well-formed, so we delay checking of these property

change, but now we'll get linker errors if we add a statement but
forget to introduce its instantiation logic.

template, introduce that member function into the template
instantiation stack. Also, add diagnostics showing the member function
within the instantiation stack and clean up the qualified-name
printing so that we get something like:
