Douglas Gregor cd0d826001 Finish implementing (de-)serialization of the CXXDefinitionData bits
needed for implicit move constructors and move assignment
operators. Fixes PR10847.

Douglas Gregor 146b8e9a58 When performing a derived-to-base cast on the right-hand side of the
synthesized move assignment within an implicitly-defined move
assignment operator, be sure to treat the derived-to-base cast as an
xvalue (rather than an lvalue). Otherwise, we'll end up getting the
wrong constructor.

Optimize a direct call to a trivial move assignment operator to an
aggregate copy, as we do for trivial copy assignment operators, and
update the the assertion in CodeGenFunction::EmitAggregateCopy() to
cope with this optimization.

Fixes PR10860.

Peter Collingbourne 2e8201422d Add missing dependency
Spotted by Ninja.

Peter Collingbourne fa9771ffec Add the resource directory to the search path for Driver::GetFilePath,
as well as the search path printed by -print-search-dirs.

The main purpose of this change is to cause -print-file-name=include
to print the path to the include directory under Clang's resource
directory, instead of the system compiler's include directory, whose
header files Clang may not be able to parse.  Some build scripts will
do something like:
  $(CC) -nostdinc -I`$(CC) -print-file-name=include`
to exclude all header paths except the compiler's.

Richard Smith a528507418 Implement the suggested resolution of WG21 N3307 issue 19: When determining whether a class is an aggregate in C++0x, treat all functions which are neither deleted nor defaulted as user-provided, not just special member functions. The wording of the standard only defines the term "user-provided" for special member functions, but the intent seems to be that any function can be user-provided.

Argyrios Kyrtzidis b914e3bc5c Handle a code-completion token being passed to the macro stringify operator.
Fixes http://llvm.org/PR10826.

Argyrios Kyrtzidis 5cec2aea3f Support code-completion for C++ inline methods and ObjC buffering methods.
Previously we would cut off the source file buffer at the code-completion
point; this impeded code-completion inside C++ inline methods and,
recently, with buffering ObjC methods.

Have the code-completion inserted into the source buffer so that it can
be buffered along with a method body. When we actually hit the code-completion
point the cut-off lexing or parsing.

Argyrios Kyrtzidis a3deaeeb52 Fix Lexer::ComputePreamble when MaxLines parameter is non-zero.

Chandler Carruth d551d4e1da Teach -Wdangling-field to warn about temporaries bound to references as
well.

Also, clean up the flow of the code a bit, and factor things more
nicely.

Finally, add the test case that was missing from my previous
commit (sorry), with new tests added to cover temporaries and other fun
cases.

Chandler Carruth 599deef379 Add a simple new warning to catch blatantly dangling pointer and
reference members of classes. We've had several bugs reported because of
this, and there's no reason not to flag it right away in the compiler.

Comments especially welcome on the strategy for implementing this
warning (IE, what should trigger this?) and on the text of the warning
itself.

I'm going to extend this to cover obvious cases with temporaries and
beef up the test cases some in subsequent patches. I'll then run it over
a large codebase and make sure its not misbehaving before I add it to
-Wall or turn it on by default. I think this one might be a good
candidate for on by default.

Douglas Gregor 8835e03cee Always construct an ASTReader with a non-NULL ASTContext and
Preprocessor, eliminating the constructor that was used by ASTUnit
(which didn't provide an ASTContext or Prepreprocessor). Ensuring that
both objects are non-NULL will simplify module loading (but none of
that is done yet).

Douglas Gregor 7018d5bcfb Teach ASTContext and Preprocessor to hold on to references to the same

Preprocessor before we know all of the LangOptions.
