VariadicMethodTypeChecker: don't warn for null pointer constants passed to variadic Objective-C methods.

llvm-svn: 127719

Remove warning for null characters in CFString literals.  Clang handles them just fine, and GCC 4.2 doesn't warn here either.

We added this warning back in 2007 when we were comparing against GCC 4.0.

make sure that upcasts of member pointer types are covered as constants.

Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented.
This completes noexcept specification work.

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.

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.

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.

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.

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