Fix PR15291: noreturn adjustment in overload resolution for function templates, from Alexander Zinenko!

VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file.  Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.

This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers.  Therefore, a new syntax is made available for directives, for
example:

// expected-error@file:line {{diagnostic message}}

This extends the @line feature where "file" is the file where the diagnostic
is generated.  The @line syntax is still available and uses the current file
for the diagnostic.  "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think!  The #include search
paths will be used to locate the file and if it is not found an error will be
generated.

The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified.  Therefore, a number of test-cases
have been updated with regard to this.

This closes out PR15613.

We currently emit an error message when you try to use thread local
storage on targets that don't support it and testing C++11 thread
locals will trip this. We don't want to xfail the test for all darwin
hosts so add a quick hack to check for darwin10 and disable the
test based on that. Only checking darwin10 because anything earlier
is really old and I don't have a list of what other hosts don't

Correct the range returned by ParmVarDecl::getSourceRange(), for parameters in ObjC methods with postfix types.

For a parameter in a method like this:

-(int)methodWithFn:(void (*)(int *p))fn;

When we are in a implementation, we check the global method pool whether there were category
methods with the same selector. If there were none (common case) we don't need to do lookups for
overridden methods again.

Note that for an interface method (if we don't encounter its implementation), it is considered that
it overrides methods that were declared before it, not for category methods introduced after it.

This is tradeoff in favor of performance, since it is expensive to do lookups in case there was a
category, and moving the global method pool to ASTContext (so we can check it) would increase complexity.

Enhance the ObjC global method pool to record whether there were 0, 1, or >= 2 methods (with a particular selector) inside categories.

This is done by extending ObjCMethodList (which is only used by the global method pool) to have 2 extra bits of information.
We will later take advantage of this info in global method pool for the overridden methods calculation.

This is an opt-in tweak for leak diagnostics to reference the allocation
site if the diagnostic consumer only wants a pithy amount of information,
and not the entire path.

This is a strawman enhancement that I expect to see some experimentation
with over the next week, and can go away if we don't want it.

Currently it is only used by RetainCountChecker, but could be used
by MallocChecker if and when we decide this should stay in.

Model it as throwing so that the exception can be caught.

This is generally not expected to have significant code-size
impact because the contents of the @autoreleasepool block
are very likely to contain a call, very likely at the same

Changes necessary to arm_neon.td for the generation of Neon tests.

This is the first of six patches to add to the arm neon tablegen
generator the capability of generating tests to verify that the various
ARM intrinsics are implemented properly.

The changes include such items as:
  1. Adding attributes to the Inst record so that additional metadata that is only
     needed for the tests can be specified in TableGen.
  2. Adding wrapper classes for operator (i.e. ``Op'') intrinsics which before
     were simply notates as Inst. This allows us to classify what sort of test
     to generate for said intrinsic and further since the classes do not effect
     the behavior of the Inst base class, allow for normal functioning.

This broke e.g. compiling a crash report from a glibc system on Darwin. Sadly,
the implementation had to game the lexer a lot as we're not using a real
preprocessor here. It also doesn't handle special cases like arbitrary macros in
__has_include, but since this macro isn't common outside of clang's headers we
can get away with that.
