CodeGen: refactor DwarfException
DwarfException served as a base class for exception handling directive emission.
However, this is also used by other exception models (e.g. Win64EH). Rename
this class to EHStreamer and split it out of DwarfException.h. NFC.
Use the opportunity to fix up some of the documentation comments to match
current LLVM style. Also rename some functions to conform better with current

Allow lookup into dependent bases in more places under -fms-compatibility
We currently allow unqualified lookup for instance methods but not
static methods because we can't recover with a semantic 'this->'
insertion.
ATL headers have static methods that do unqualified lookup into
dependent base classes. The pattern looks like:
template <typename T> struct Foo : T {
static int *getBarFromT() { return Bar; }
};
Now we recover as if the user had written:
template <typename T> struct Foo : T {
static int *getBarFromT() { return Foo::Bar; }
};
... which will eventually look up Bar in T at instantiation time.
Now we emit a diagnostic in both cases, and delay lookup in other
contexts where 'this' is available and refers to a class with dependent
bases.

Fix a bug in the Thumb1 ARM Load/Store optimizer
Previously, the basic block was searched for future uses of the base register,
and if necessary any writeback to the base register was reset using a SUB
instruction (e.g. before calling a function) just before such a use. However,
this step happened *before* the merged LDM/STM instruction was built. So if
there was (e.g.) a function call directly after the not-yet-formed LDM/STM,
the pass would first insert a SUB instruction to reset the base register,

[PPC64LE] Recognize shufflevector patterns for little endian
Various masks on shufflevector instructions are recognizable as
specific PowerPC instructions (vector pack, vector merge, etc.).
There is existing code in PPCISelLowering.cpp to recognize the correct
patterns for big endian code. The masks for these instructions are
different for little endian code due to the big-endian numbering
employed by these instructions. This patch adds the recognition code
for little endian.
I've added a new test case test/CodeGen/PowerPC/vec_shuffle_le.ll for
this. The existing recognizer test (vec_shuffle.ll) is unnecessarily
verbose and difficult to read, so I felt it was better to add a new
test rather than modify the old one.

Add detection of OS X relocatable SDK to compiler-rt as a lit.util function
Clang's lit cfg already detects the currently selected SDK via
"xcrun --show-sdk-path". The same thing should be done for compiler-rt tests,
to make them work on recent OS X versions. Instead of duplicating the detection
code, this patch extracts the detection function into a lit.util method.

Condition codes AL and NV are invalid in the aliases that use
inverted condition codes (CINC, CINV, CNEG, CSET, and CSETM).
Matching aliases based on "immediate classes", when disassembling,
wasn't previously supported, hence adding MCOperandPredicate
into class Operand, and implementing the support for it
in AsmWriterEmitter.
The parsing for those aliases was already custom, so just adding
the missing condition into AArch64AsmParser::parseCondCode.

X86: elide comparisons after cmpxchg instructions.
The C++ and C semantics of the compare_and_swap operations actually
require us to return a boolean "success" value. In LLVM terms this
means a second comparison of the output of "cmpxchg" against the input
desired value.
However, x86's "cmpxchg" instruction sets all flags for the comparison
formed, so we can skip any secondary comparison. (N.b. this isn't true
for cmpxchg8b/16b, which only set ZF).
