Nico Weber b2c53d3393 Make __shiftleft128 / __shiftright128 real compiler built-ins.
r337619 added __shiftleft128 / __shiftright128 as functions in intrin.h.
Microsoft's STL plans on using these functions, and they're using intrin0.h
which just has declarations of built-ins to not pull in the huge intrin.h
header in the standard library headers. That requires that these functions are
real built-ins.

Nico Weber e5898c1911 [ms] Add __shiftleft128 / __shiftright128 intrinsics
Carefully match the pattern matched by ISel so that this produces shld / shrd
(unless Subtarget->isSHLDSlow() is true).

Thanks to Craig Topper for providing the LLVM IR pattern that gets successfully
matched.

Fixes PR37755.

Martin Storsjo 64a5499587 [Headers] Add a test for arm64intr.h
This tests the ARM64 specific constants added in SVN r309081,
similar to the one added in r277928 for armintr.h.

Albert Gutowski 1deab38717 Implement __stosb intrinsic as a volatile memset
Summary: We need `__stosb` to be an intrinsic, because SecureZeroMemory function uses it without including intrin.h. Implementing it as a volatile memset is not consistent with MSDN specification, but it gives us target-independent IR while keeping the most important properties of `__stosb`.

Saleem Abdulrasool afdef205d8 Headers: Add ARM support to intrin.h for MSVC compatibility
This fixes compiling with headers from the Windows SDK for ARM, where the
YieldProcessor function (in winnt.h) refers to _ARM_BARRIER_ISHST.

The actual MSVC armintr.h contains a lot more definitions, but this is enough to
build code that uses the Windows SDK but doesn't use ARM intrinsics directly.

An alternative would to just keep the addition to intrin.h (to include
armintr.h), but not actually ship armintr.h, instead having clang's intrin.h
include armintr.h from MSVC's include directory. (That one works fine with
clang, at least for building code that uses the Windows SDK.)

Nico Weber 1f22a34409 ms Intrin.h: Fix __movsw's and __stosw's inline asm.
Before, clang's internal assembler would reject the inline asm in clang's
Intrin.h.  To make sure this doesn't happen for other Intrin.h functions using
__asm__ blocks, add 32-bit and 64-bit codegen tests for Intrin.h.

Sadly, these tests discovered that __readcr3 and __writecr3 have bad
implementations in 64-bit builds.  This will have to be fixed in a follow-up.

Saleem Abdulrasool c68237bc2c 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.

Saleem Abdulrasool 074736f576 test: merge arm-intrin into ms-intrin, fix invocation
This merges the two tests into one since there is no real reason to separate
them.  It also fixes the test invocation to specify -fms-compatibility without
which we would end up without an Intrin.h header.

Hans Wennborg dd0f5304f6 MS intrinsics: don't declare __readeflags and __writeeflags in Intrin.h
They're already defined in ia32intrin.h, and this would cause including Intrin.h
in 64-bit mode to fail because of conflicting types. Update ms-intrin.cpp to
also run in 64-bit mode to catch things like this.

Hans Wennborg aae6ac48e7 Relax the ms-intrin.cpp test
The part that checks that certain functions are marked deprecated doesn't
seem that useful, and it has the bad effect that the test hard-coded the
locations of the notes from that test.

Ted Kremenek b79ee57080 Implemented delayed processing of 'unavailable' checking, just like with 'deprecated'.
Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.

This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings.  By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent.  It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.

This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated".  It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
 (e.g., "function" instead of "destructor").  By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away.  This diagnostic can likely be further wordsmithed
to be shorter.

Reid Kleckner 00d33a5cb1 Add implementations of the MSVC barrier intrinsics
Summary:
These are deprecated in VS 2012 according to MSDN.  They don't actually
compile down to any code.  They prevent the compiler from reordering
memory accesses across the barrier, which is what a memory-clobbering
volatile asm does.

Chandler Carruth 2c93cb2a6f Switch tests in test/Headers to use %clang_cc1 rather than %clang. There
is no need to go through the driver indirection here, and it clutters
things up as dependencies can sneak in for specific things the driver is
doing.
