Alp Toker 6ed7251683 Revert "Don't require -re suffix on -verify directives with regexes."
This patch was submitted to the list for review and didn't receive a LGTM.

(In fact one explicit objection and one query were raised.)

This reverts commit r197295.

Hans Wennborg cda4b6dd00 Change semantics of regex expectations in the diagnostic verifier
Previously, a line like

  // expected-error-re {{foo}}

treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".

This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.

(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

Richard Smith b2504bdc0d Issue a diagnostic if an implicitly-defined move assignment operator would move
the same virtual base class multiple times (and the move assignment is used,
and the move assignment for the virtual base is not trivial).

Richard Smith 8b86f2d401 Implement final resolution of DR1402: implicitly-declared move operators that
would be deleted are still declared, but are ignored by overload resolution.

Also, don't delete such members if a subobject has no corresponding move
operation and a non-trivial copy. This causes us to implicitly declare move
operations in more cases, but risks move-assigning virtual bases multiple
times in some circumstances (a warning for that is to follow).

Richard Smith 114394f824 Implement [class.friend]p11's special name lookup rules for friend declarations
of local classes. We were previously handling this by performing qualified
lookup within a function declaration(!!); replace it with the proper scope
lookup.

Richard Smith 1ad04d95bc PR12625: Cope with classes which have incomplete base or member types:
Don't try to query whether an incomplete type has a trivial copy constructor
when determining whether a move constructor should be declared.

Richard Smith 83c478d389 Fix bug where a class's (deleted) copy constructor would be implicitly given a
non-const reference parameter type if the class had any subobjects with deleted
copy constructors. This causes a rejects-valid if the class's copy constructor
is explicitly defaulted (as happens for some implementations of std::pair etc).

Richard Smith f989e51cb6 PR10217 diagnostic fix: don't say 'copy constructor' when we mean
'copy assignment operator'.

Richard Smith 6f1e2c6d19 Finish PR10217: Ensure we say that a special member was implicitly, not
explicitly, deleted in all relevant cases, and explain why.

Richard Smith cf8ec8dad6 Implement DR1402: if a field or base class is not movable, the derived class's
move constructor/move assignment operator are not declared, rather than being
defined as deleted, so move operations on the derived class fall back to
copying rather than moving.

If a move operation on the derived class is explicitly defaulted, the
unmovable subobject will be copied instead of being moved.

Douglas Gregor 74f7d50f6a When overload resolution picks an implicitly-deleted special member
function, provide a specialized diagnostic that indicates the kind of
special member function (default constructor, copy assignment
operator, etc.) and that it was implicitly deleted. Add a hook where
we can provide more detailed information later.

Sebastian Redl 22653bac1a Declare and define implicit move constructor and assignment operator.
This makes the code duplication of implicit special member handling even worse,
but the cleanup will have to come later. For now, this works.
Follow-up with tests for explicit defaulting and enabling the __has_feature
flag to come.
