Argyrios Kyrtzidis 75627ad8ba Fix the rewriter that broke with r149987.
r149987 changed the way parsing happens inside an @implementation;
it aggregates the declarations inside and reports them together as a DeclGroup.
This had the side effect that function declarations were reported together with
their definition, while the rewriter expected for function declarations to be
reported immediately to the consumer and thus not have a body.

Fix this by having the rewriter actually check with isThisDeclarationADefinition()
to make sure the body comes from the current decl before rewriting it.

Sebastian Redl a935179ab7 Represent C++ direct initializers as ParenListExprs before semantic analysis
instead of having a special-purpose function.

- ActOnCXXDirectInitializer, which was mostly duplication of
  AddInitializerToDecl (leading e.g. to PR10620, which Eli fixed a few days
  ago), is dropped completely.
- MultiInitializer, which was an ugly hack I added, is dropped again.
- We now have the infrastructure in place to distinguish between
  int x = {1};
  int x({1});
  int x{1};
-- VarDecl now has getInitStyle(), which indicates which of the above was used.
-- CXXConstructExpr now has a flag to indicate that it represents list-
   initialization, although this is not yet used.
- InstantiateInitializer was renamed to SubstInitializer and simplified.
- ActOnParenOrParenListExpr has been replaced by ActOnParenListExpr, which
  always produces a ParenListExpr. Placed that so far failed to convert that
  back to a ParenExpr containing comma operators have been fixed. I'm pretty
  sure I could have made a crashing test case before this.

The end result is a (I hope) considerably cleaner design of initializers.
More importantly, the fact that I can now distinguish between the various
initialization kinds means that I can get the tricky generalized initializer
test cases Johannes Schaub supplied to work. (This is not yet done.)

This commit passed self-host, with the resulting compiler passing the tests. I
hope it doesn't break more complicated code. It's a pretty big change, but one
that I feel is necessary.

Sebastian Redl 46afb55177 Drive-by fix of incorrect diagnostic, and a test case for said diagnostic. The double error is unfortunate, but I really don't see an alternative whose effort is worth it.

Sebastian Redl 82ace98d55 Fix parsing new expressions using init lists. Probably still do the wrong thing in cases involving array new.
Show that many cases using initializer list constructors work, in that they parse and pass semantic analysis.

must be implicitly captured.

Richard Smith 63168c7533 PR11684, core issue 1417:
o Correct the handling of the restrictions on usage of cv-qualified and
  ref-qualified function types.
o Fix a bug where such types were rejected in template type parameter default
  arguments, due to such arguments not being treated as a template type arg
  context.
o Remove the ExtWarn for usage of such types as template arguments; that was
  a standard defect, not a GCC extension.
o Improve the wording and unify the code for diagnosing cv-qualifiers with the
  code for diagnosing ref-qualifiers.

Richard Smith 5e580292ac Track whether a function type has a trailing return type as type sugar. Use this
to pretty-print such function types better, and to fix a case where we were not
instantiating templates in lexical order. In passing, move the Variadic bit from
Type's bitfields to FunctionProtoType to get the Type bitfields down to 32 bits.
Also ensure that we always substitute the return type of a function when
substituting explicitly-specified arguments, since that can cause us to bail
out with a SFINAE error before we hit a hard error in parameter substitution.

David Blaikie 54f5d859ad Move -Wswitch from -Wmost to -Wall, consitent with GCC.
This is a relatively noisy warning for a codebase not explicitly designed for
it (effectively enforcing a stylistic constraint about the use of defaults
in switches over enums) & there's nothing Clang does to clean up the noise
when compared to GCC's implementation so the same decision seems suitable.
