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.

RUN: foo
RUN: bar || true
is equivalent to:
RUN: foo && bar || true
which is equivalent to:
RUN: (foo && bar) || true
This resulted in several of the fixit tests not really testing anything.

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.

a very large chunk of code and found zero false positives. I've only
found a few bugs, but that likely is because bugs of this nature
actually do manifest. We've also identified several bugs that were
caught by Valgrind, but would have been caught faster and more easily
with this warning.
If anyone has concerns, or this causes fallout on any build bots, lemme
know. I'm happy to just put it under -Wmost.

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.

The function was only counting lines that included tokens and not empty lines,
but MaxLines (mainly initiated to the line where the code-completion point resides)
is a count of overall lines (even empty ones).

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.

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.

Remove TransferFuncs from ExprEngine and AnalysisConsumer.
Demote RetainReleaseChecker to a regular checker, and give it the name osx.cocoa.RetainCount (class name change coming shortly). Update tests accordingly.

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).

builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

and language-specific initialization. Use this to allow ASTUnit to
create a preprocessor object *before* loading the AST file. No actual
functionality change.
