Richard Smith fd3dae024f Finish implementation of C++ DR1310 (http://wg21.link/cwg1310).
Diagnose the case when a dependent template name instantiates to an
injected-class-name outside a nested-name-specifier.

Richard Smith 11255ec765 PR9551: Implement DR1004 (http://wg21.link/cwg1004).
This rule permits the injected-class-name of a class template to be used as
both a template type argument and a template template argument, with no extra
syntax required to disambiguate.

Richard Smith 122f88d481 [c++17] P0135R1: Guaranteed copy elision.
When an object of class type is initialized from a prvalue of the same type
(ignoring cv qualifications), use the prvalue to initialize the object directly
instead of inserting a redundant elidable call to a copy constructor.

Richard Smith 5a0e50cd87 DR1048: drop top-level cv-qualifiers when deducing the return type of a
lambda-expression in C++11, to match the C++14 rules.

Richard Smith 454a7cdfb3 Implement DR990 and DR1070. Aggregate initialization initializes uninitialized
elements from {}, rather than value-initializing them. This permits calling an
initializer-list constructor or constructing a std::initializer_list object.
(It would also permit initializing a const reference or rvalue reference if
that weren't explicitly prohibited by other rules.)
