UninitializedValues: introduce ValueVector:reference class to forward to llvm::BitVector.  No real functionality change, but this is a stepping stone to moving to tri-state logic.

llvm-svn: 127665

UninitializedValues: wrap BitVector references in a new class ValueVector.  No functionality change.  This defines the minimum interface that ValueVector needs to support when we no longer base it strictly on a direct interpretation of BitVector.

llvm-svn: 127664

Substitue term "BitVector" with "ValueVector" to prep for further revisions.  No functionality change.

lib/Basic/Targets.cpp: __declspec(attr) should be provided on mingw as macro, alias of __attribute__.

On mingw without -fms-extensions, we can provide "as-is" __declspec.

lib/Headers/mm_malloc.h: On Windows, we can expect _mm_malloc would be provided as macro by <malloc.h>.

replace some uses of FieldOffsetInBytes. The remaining uses of
FieldOffsetInBytes will be replaced once NextFieldOffsetInBytes is converted
to CharUnits. No change in functionality intended.

After the open+fstat optimization, files were already opened for FileManager::getBufferForFile() and we closed them after reading them.
The problem was that when -working-directory was passed, the code path that actually reuses & closes the already opened file descriptor
was not followed.

cannot yet be resolved, be sure to push the new label declaration into
the right place within the identifier chain. Otherwise, name lookup in
C++ gets confused when searching for names that are lexically closer
than the label. Fixes PR9463.

Tweak VariadicMethodTypeChecker to only create one ExplodedNode when issuing multiple warnings for the same message expression.

Also add a test case showing that we correctly report multiple warnings for the same message expression.

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

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
