Previously, only -1 and +1 step values are supported for induction variables. This patch extends LV to support
arbitrary constant steps.
Initial patch by Alexey Volkov. Some bug fixes are added in the following version.

Fatal errors disable all further diagnostics. Continuing to permit
template instantiation does nothing but make it take longer for clang to
finish with the TU.
Instead, halt all further instantiation.
Fixed in PR22396.

SimpleFileWrapper was a class to wrap an existing (possibly non-mutable)
file as a mutable file. We used instances of the class in RoundTrip*
passes, because the passes convert mutable files to non-mutable files,
and we needed to convert them back to mutable.
That feature can be implemented without defining a new class. Generally
speaking, if we can implement a feature without defining a class and
using only public interface of exsiting classes, that's preferred way
to do that. And this is the case.

accumulateAndSortLibcalls in LTOCodeGenerator.cpp collects names of runtime
library functions which are used to identify user-defined functions that should
be protected. Previously, this function would only scan the TargetLowering
object belonging to the "main" subtarget for the library function names. This
commit changes it to scan all per-function subtargets.

In the large code model, we now put __chkstk in %r11 before calling it.
Refactor the code so that we only do this once. Simplify things by using
__chkstk_ms instead of __chkstk on cygming. We already use that symbol
in the prolog emission, and it simplifies our logic.
Second half of PR18582.

Summary:
The PS4 defaults to -fno-rtti, and has to have rtti enabled when enabling
exceptions.
This commit makes clang add the -fno-rtti by default on the PS4, unless
-frtti was passed in.
It also diagnoses misuses for the PS4:
- Exceptions need rtti. Warn and enable rtti if no rtti flag was passed,
error if -fno-rtti was passed.
I also added a more general warning for when -fno-rtti is the default
(currently it's only on the PS4) and the vptr sanitizer is on.
Fixed a few tests, due to different flag order when passing cc1 arguments.

calls that don't take a Function argument from Mips. Notable
exceptions: the AsmPrinter and MipsTargetObjectFile. The
latter needs to be fixed, and the former will be fixed when the
general AsmPrinter changes happen.

between the linker's TLS optimizations and Clang's TLS code generation.
For now, Clang has been changed to disable linker TLS optimizations
until it (and LLVM more generally) are emitting TLS code sequences
compatible with the old bugs found in the linkers. That's a better fix
to handle bootstrapping on that platform.

In both CMake and Makefiles, we are inconsistent about the use of libstdc++ vs. libc++, SDKs and minimum deployment targets for OS X. Let's fix the detection of SDKs, and let's explicitely set that we link against libc++ and mmacosx-version-min is 10.7.
