Now, for IR like:

[mips][fp64a] Temporarily disable odd-numbered double-precision registers when using the FP64A ABI.
Summary:
A few instructions (mostly cvt.d.w and similar) are causing problems with
-mfp64 and -mno-odd-spreg and it looks like fixing it properly may
take several weeks. In the meantime, let's disable the odd-numbered
double-precision registers so that the generated code is at least valid.
The problem is that instructions like cvt.d.w read from the 32-bit low
subregister of a double-precision FPU register. This often leads to the compiler
to inserting moves to transfer a GPR32 to a FGR32 using mtc1. Such moves
violate the rules against 32-bit writes to odd-numbered FPU registers imposed
by -mno-odd-spreg. By disabling the odd-numbered double-precision registers, it
becomes impossible for the 32-bit low subregister to be odd-numbered.
This fixes numerous test-suite failures when compiling for the FP64A ABI
('-mfp64 -mno-odd-spreg'). There is no LLVM test case because it's difficult to
test that odd-numbered FPU registers are not allocatable. Instead, we depend on
the assembler (GAS and -fintegrated-as) raising errors when the rules are
violated.

Driver: bifurcate extended and basic MSC versioning
This restores the original behaviour of -fmsc-version. The older option
remains as a mechanism for specifying the basic version information. A
secondary option, -fms-compatibility-version permits the user to specify an
extended version to the driver.
The new version takes the value as a dot-separated value rather than the
major * 100 + minor format that -fmsc-version format. This makes it easier to
specify the value as well as a more flexible manner for specifying the value.
Specifying both values is considered an error.
The older parameter is left solely as a driver option, which is normalised into
the newer parameter. This allows us to retain a single code path in the
compiler itself whilst preserving the semantics of the old parameter as well as
avoid having to determine which of two formats are being used by the invocation.
The test changes are due to the fact that the compiler no longer supports the
old option, and is a direct conversion to the new option.

Perform wildcard expansion in Process::GetArgumentVector on Windows (PR17098)
On Windows, wildcard expansion isn't performed by the shell, but left to the
program itself. The common way to do this is to link with setargv.obj, which
performs the expansion on argc/argv before main is entered. However, we don't
use argv in Clang on Windows, but instead call GetCommandLineW so we can handle
unicode arguments. This means we have to do wildcard expansion ourselves.
A test case will be added on the Clang side.

Fixed the an objective C test case so it passes correctly.
Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.

Clang uses a diagnostic handler to grab diagnostic messages so it can print them

Move Post RA Scheduling flag bit into SchedMachineModel
Refactoring; no functional changes intended

Removed enablePostRAScheduler() function from TargetSubtargetInfo and subclasses.

Added methods to TargetSubtargetInfo to allow overrides for AntiDepBreakMode, CriticalPathRCs, and OptLevel for PostRAScheduling.
Added enablePostRAScheduler() function to PostRAScheduler class which queries the subtarget for the above values.
Preserved existing scheduler behavior for ARM, MIPS, PPC, and X86:
a. ARM overrides the CPU's postRA settings by enabling postRA for any non-Thumb or Thumb2 subtarget.
b. MIPS overrides the CPU's postRA settings by enabling postRA for everything.
c. PPC overrides the CPU's postRA settings by enabling postRA for everything.
d. X86 is the only target that actually has postRA specified via sched model info.
