This moves all of the PassManager <-> Target communication to use the
new pass manager's TargetIRAnalysis even with the old pass manager. See
the LLVM commit for some of why things are moving in this direction, but
the short version is that this will enable us to create per-function
TargetTransformInfo objects that have correct subtarget information for
that function.

Create a new TargetCodeGenInfo for Windows on ARM to permit annotating the
functions with stack-probe-size (for /Gs and -mstack-probe-support) for
generating the stack probe necessary for Windows targets. This will be used by
the backend when lowering the frame to generate the stack probe appropriately.

Even with r227555, this still crashed:
struct S {
int A;
~A::A() {}
};
That's because ParseOptionalCXXScopeSpecifier()'s call to
ActOnCXXNestedNameSpecifier() doesn't mark the scope spec as invalid if sema
thought it's a good idea to fixit-correct "::" to ":". For the diagnostic
improvement done in r217302, we never want :: to be interpreted as :, so fix
this by setting ColonSacred to false temporarily.

In OpenCL 1.2, using double no longer requires using the pragma cl_khr_fp64,
instead a kernel is allowed to use double, but must first have queried
clGetDeviceInfo's CL_DEVICE_DOUBLE_FP_CONFIG.
Page 197, section 6.1.1 of the OpenCL 1.2 specification has a footnote 23
describing this behaviour.
I've also added test cases such that the pragma must be used if targeting
OpenCL 1.0 or 1.1, but is ignored in 1.2 and 2.0.

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.

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.

Work around a bug in GNU ld (and gold) linker versions up to 2.25
that may mis-optimize code generated by this version of clang/LLVM
to access general-dynamic or local-dynamic TLS variables.
Bug is fixed here:
