The previous syntax created a list with the usual semicolon as
separator, which breaks the link command.

Add an Objective-C checker that checks that arguments passed to some variadic Objective-C methods are of Objective-C pointer types.

Ted or Argiris, I'd appreciate a review!

We were dropping the expansion of -rpath=$(LibDir) on linux, which resulted in
the build not being able to resolve libLLVM.so.  Bring in the definition before
expanding the values hanging off LD.Flags.

Thanks to Jason E. Aten for reporting this!

Instead of storing an ASTContext* in FunctionProtoTypes with computed noexcept specifiers, unique FunctionProtoTypes with a ContextualFoldingSet, as suggested by John McCall.

On Windows only the shared library is created. The reason for this is
that clang.lib the static library would clash with clang.lib the
export library of the dll.

load and store reference same memory location, the memory location
is represented by getelementptr with two uses (load and store) and
the getelementptr's base is alloca with single use. At this point,
instructions from alloca to store can be removed.
(this pattern is generated when bitfield is accessed.)
For example,
%u = alloca %struct.test, align 4               ; [#uses=1]
%0 = getelementptr inbounds %struct.test* %u, i32 0, i32 0;[#uses=2]
%1 = load i8* %0, align 4                       ; [#uses=1]
%2 = and i8 %1, -16                             ; [#uses=1]
%3 = or i8 %2, 5                                ; [#uses=1]
store i8 %3, i8* %0, align 4

Fix CFG assertion failure reported in PR 9467.  This was due to recent changes in optimizing CFGs for switch statements.

Use the virtual register number as a cache tag instead. They are not reused.

This allows the allocator to free any resources used by the virtual register,
including physical register assignments.

Remove optimization emitting a reference insted of label difference, since
it can create more relocations. Removed isBaseAddressKnownZero method,

Change the interface to expose the new information and deal with the enormous fallout.
Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications.
Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support.
