It's possible to have multiple local ObjCLifetime qualifiers. When there is
a conflict, we can't stop after we reach a type that is directly qualified.
We need to keep pulling sugar off and removing the ObjCLifetime qualifers.

Adding front-end support to several intrinsics (bit scanning, conversion and state reading intrinsics)


Adding LLVM front-end support to two intrinsics dealing with bit scan: _bit_scan_forward and _bit_scan_reverse.
 Their functionality is as described in Intel intrinsics guide:
 https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_bit_scan_forward&expand=371,370
 https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_bit_scan_reverse&expand=371,370

 Furthermore, adding clang front-end support to these conversion intrinsics: _mm256_cvtsd_f64, _mm256_cvtsi256_si32 and _mm256_cvtss_f32.

 Finally, adding tests to all of the above, as well as to the state reading intrinsics _rdpmc and _rdtsc.
  Their functionality is also specified in the Intel intrinsics guide.

The `isa' member was previously not given the correct DLL Storage.  Ensure that
we give the `isa' constant `__CFConstantStringClassReference' the correct DLL
storage.  Default to dllimport unless an explicit specification gives it a
dllexport storage.

If a closing ')' isn't found for a macro instantiation inside a '[',
the next token is EOF, this leads to crashes if we try to look ahead of
that. This could be triggered whenever trying to parse lambdas or objs
message expressions.

When we import a module that defines a builtin identifier from prefix header and
precompile the prefix header, the macro information related to the identifier
is lost.

If we don't precompile the prefix header, the source file can still see the
macro information. The reason is that we write out the identifier in the pch
but not the macro information since the macro is not defined locally.

This is related to r251565. In that commit, if we read a builtin identifier from
a module that wasn't "interesting" to that module, we will still write it out to
a PCH that imports that module.

The fix is to write exported module macros for PCH as well.

Previous attempts to rename the IBOutletCollection argument to something
other than "Interface" were undone (r127127 and r139620).  Instead of
renaming it, work around this in tablegen, so the public facing getter
can have the usual name of 'getInterface'.

Summary:
When a replacement's offset is set to UINT_MAX or -1U, it is treated as
a header insertion replacement by cleanupAroundReplacements(). The new #include
directive is then inserted into the correct block.

According to the gcc headers, intel intrinsics docs and msdn codegen the _mm_store1_pd (and its _mm_store_pd1 equivalent) should use an aligned pointer - the clang headers are the only implementation I can find that assume non-aligned stores (by storing with _mm_storeu_pd).

Additionally, according to the intel intrinsics docs and msdn codegen the _mm_store1_ps (_mm_store_ps1) requires a similarly aligned pointer.

This patch raises the alignment requirements to match the other implementations by calling _mm_store_ps/_mm_store_pd instead.

I've also added the missing _mm_store_pd1 intrinsic (which maps to _mm_store1_pd like _mm_store_ps1 does to _mm_store1_ps).

As a followup I'll update the llvm fast-isel tests to match this codegen.
