Richard Smith 410cc89374 [c++1z] Most of N4268 (allow constant evaluation for non-type template arguments).
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.

Richard Smith 0b3a46247e PR21437, final part of DR1330: delay-parsing of exception-specifications. This
is a re-commit of Doug's r154844 (modernized and updated to fit into current
Clang).

Richard Smith 13307f5f24 [c++1z] Implement nested-namespace-definitions.
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.

Richard Smith d20f1e6dd3 PR21327 / C++ DR1652 / C++ DR73: comparing a past-the-end pointer for one
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.

Richard Smith 0daabd7ebe Don't perform ADL when looking up operator=; there is no non-member form of
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.

Richard Smith 091405d7e3 Reword switch/goto diagnostics "protected scope" diagnostics. Making up a term
"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.

implement the intent of the DR.)

David Majnemer 742424339a Sema: Disallow taking the address of a bitfield coming from preincrement
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.

Nico Weber 9386c82d56 Improve diagnostic on default-initializing const variables (PR20208).
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.

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.)

Alp Toker 71c53d472f Fix the undefined-but-used odr-use marker (DR48)
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).
