Larisse Voufo 19d0867284 Implement the remaining portion of DR1467 from r227022. I may have overlooked a few things, but this implementation comes straight from the DR resolution itself.

Richard Smith 8d082d187e PR20844: If we fail to list-initialize a reference, map to the referenced type
before retrying the initialization to produce diagnostics. Otherwise, we may
fail to produce any diagnostics, and silently produce invalid AST in a -Asserts
build. Also add a note to this codepath to make it more clear why we were
trying to create a temporary.

Serge Pavlov 750db65bac Warn on duplicate function specifier
This patch fixes PR8264. Duplicate qualifiers already are diagnozed,
now the same diagnostics is issued for duplicate function specifiers.

Richard Smith 089c31637f PR17295: Do not allow explicit conversion functions to be used in cases where
an additional conversion (other than a qualification conversion) would be
required after the explicit conversion.

Conversely, do allow explicit conversion functions to be used when initializing
a temporary for a reference binding in direct-list-initialization.

Richard Smith ccc1181105 Refactor places which perform contextual implicit conversions to go through a
common function. The C++1y contextual implicit conversion rules themselves are
not yet implemented, however.

This also fixes a subtle bug where template instantiation context notes were
dropped for diagnostics coming from conversions for integral constant
expressions -- we were implicitly slicing a SemaDiagnosticBuilder into a
DiagnosticBuilder when producing these diagnostics, and losing their context
notes in the process.

Douglas Gregor 6073dcab38 Implement C++11 [over.match.copy]p1b2, which allows the use of
explicit conversion functions to initialize the argument to a
copy/move constructor that itself is the subject of direct
initialization. Since we don't have that much context in overload
resolution, we end up threading more flags :(.

Fixes <rdar://problem/10903741> / PR10456.

Richard Trieu 553b2b2e5d Modify how the -verify flag works. Currently, the verification string and
diagnostic message are compared.  If either is a substring of the other, then
no error is given.  This gives rise to an unexpected case:

  // expect-error{{candidate function has different number of parameters}}

will match the following error messages from Clang:

  candidate function has different number of parameters (expected 1 but has 2)
  candidate function has different number of parameters

It will also match these other error messages:

  candidate function
  function has different number of parameters
  number of parameters

This patch will change so that the verification string must be a substring of
the diagnostic message before accepting.  Also, all the failing tests from this
change have been corrected.  Some stats from this cleanup:

87 - removed extra spaces around verification strings
70 - wording updates to diagnostics
40 - extra leading or trailing characters (typos, unmatched parens or quotes)
35 - diagnostic level was included (error:, warning:, or note:)
18 - flag name put in the warning (-Wprotocol)

Richard Smith 9ca5c42582 Update all tests other than Driver/std.cpp to use -std=c++11 rather than
-std=c++0x. Patch by Ahmed Charles!

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.

Douglas Gregor 38b2d3fa3e Tests for explicit conversion operators, along with a fix to avoid
considering explicit conversion operators when determining surrogate
functions. Fixes PR10453. Note that there are a few test cases where
Clang is still wrong because it does not implement DR899; see PR10456.

Anders Carlsson 6515d877c0 Fix a pretty bad bug where if a constructor (or conversion function) was marked as 'explicit', but then defined out-of-line, we would not treat it as being explicit.
