We don't yet support pointer-to-member template arguments that have undergone
pointer-to-member conversions, mostly because we don't have a mangling for them yet.

This allows 'namespace A::B { ... }' as a shorthand for 'namespace A {
namespace B { ... } }'. We already supported this correctly for error recovery;
promote that support to a full implementation.
This is not the right implementation: we do not maintain source fidelity
because we desugar the nested namespace definition in the parser. This is
tricky to avoid, since the definition genuinely does inject one named
entity per level in the namespace name.

complete object to a pointer to the start of another complete object does
not evaluate to the constant 'false'. All other comparisons between the
addresses of subobjects of distinct complete objects still do.

that function, and apart from being slow, this is unnecessary: ADL can trigger
instantiations that are not permitted here. The standard isn't *completely*
clear here, but this seems like the intent, and in any case this approach is
permitted by [temp.inst]p7.

"protected scope" is very unhelpful here and actively confuses users. Instead,
simply state the nature of the problem in the diagnostic: we cannot jump from
here to there. The notes explain nicely why not.

use __thiscall. (This doesn't actually work for MSVC; they don't allow the
__thiscall qualifier here, but it's sufficient to demonstrate that we do
implement the intent of the DR.)

Clang forgot that '++s.m' was a bitfield l-value and permit it's address
to be taken; this would crash at CodeGen-time.
Instead, propagate the object-kind when we see the prefix
increment/decrement.
This fixes PR20496.

This tweaks the diagnostic wording slighly, and adds a fixit on a note.
An alternative would be to add the fixit directly on the diagnostic, see
the review thread linked to from the bug for a few notes on that approach.

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.)

We should treat tentative definitions as undefined for the purpose of
ODR-use linkage checking.
This broke somewhere around r149731 when tests were disabled.
Note that test coverage for these diagnostics is generally lacking due to a
separate issue (PR19910: Don't suppress unused/undefined warnings when there
are errors).

Summary:
Naming the destructor using a typedef-name for the class-name is
well-formed.
This fixes PR19620.

Summary:
Declaring a function as inline after it has been defined is in violation
of [dcl.fct.spec]p4. The program would get a strong definition instead
of getting a function with linkonce_odr linkage.

We were previously checking at every destructor declaration, but that was a bit
excessive. Since the deleting destructor is emitted with the vtable, do the
check when the vtable is marked used.

DR18 previously forebode typedefs to be used as parameter types if they
were of type 'void'. DR577 allows 'void' to be used as a function
parameter type regardless from where it came.
