We identify the cases where the operand to an ADDE node is a constant
zero. In such cases, we can avoid generating an extra ADDu instruction
disguised as an identity move alias (ie. addu $r, $r, 0 --> move $r, $r).

[MC] Use the non-EH register mapping in the debug_frame section.
On 32bits x86 Darwin, the register mappings for the eh_frane and
debug_frame sections are different. Thus the same CFI instructions
should result in different registers in the object file. The
problem isn't target specific though, but it requires that the
mappings for EH register numbers be different from the standard
Dwarf one.
The patch looks a bit clumsy. LLVM uses the EH mapping as
canonical for everything frame related. Thus we need to do a
double conversion EH -> LLVM -> Non-EH, when emitting the

Win64: Silently ignore __stdcall, __fastcall, and __thiscall
MSVC doesn't warn on this. Users are expected to apply the WINAPI macro
to functions passed by pointer to the Win32 API, and this macro expands
to __stdcall. This means we end up with a lot of useless noisy warnings
about ignored calling conventions when compiling code with clang for
Win64.

When the source has a series of assignments, users reasonably want to
have the debugger step through each one individually. Turn off the
combine for adjacent stores at -O0 so we get this behavior.
Possibly, DAGCombine shouldn't run at all at -O0, but that's for
another day; see PR22346.

Fix justify error for small structures in varargs for MIPS64BE

The structures smaller than 64 bit were not left justified on MIPS64

Fix handling of double quotes (MI)
Summary:
* Clean CMICmdArgValString::Validate: now it's based on CMIUtilString::SplitConsiderQuotes method:
A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.
When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases.
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again.
Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.
* Enable MiInterpreterExecTestCase.test_lldbmi_target_create test
* Fix MiExecTestCase.test_lldbmi_exec_arguments_set test
All tests pass on OS X.

Use ".arch_extension" ARM directive to support hwdiv on krait
In case of "krait" CPU, asm printer doesn't emit any ".cpu" so the
features bits are not computed. This patch lets the asm printer
emit ".cpu cortex-a9" directive for krait and the hwdiv feature is
enabled through ".arch_extension". In short, krait is treated
as "cortex-a9" with hwdiv. We can not emit ".krait" as CPU since
it is not supported bu GNU GAS yet

Use ".arch_extension" ARM directive to specify the additional CPU features
This patch is in response to r223147 where the avaiable features are
computed based on ".cpu" directive. This will work clean for the standard
variants like cortex-a9. For custom variants which rely on standard cpu names
for assembly, the additional features of a CPU should be propagated. This can be
done via ".arch_extension" as long as the assembler supports it. The
implementation for krait along with unit test will be submitted in next patch.

libclc/math: Add cospi
Ported from the libclc/amd-builtins branch
v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
Add cospi(double) implementation instead of using llvm.cos
Notes:
The sincosD_piby4.h file is mostly the same as the builtin implementation
released by AMD. The inline attribute declaration is changed, and M_PI is
used instead of a constant double. Otherwise, the only difference is that
the header explicitly enables the fp64 pragma.
