Alp Toker d4a3f0e894 Hide the concept of diagnostic levels from lex, parse and sema
The compilation pipeline doesn't actually need to know about the high-level
concept of diagnostic mappings, and hiding the final computed level presents
several simplifications and other potential benefits.

The only exceptions are opportunistic checks to see whether expensive code
paths can be avoided for diagnostics that are guaranteed to be ignored at a
certain SourceLocation.

This commit formalizes that invariant by introducing and using
DiagnosticsEngine::isIgnored() in place of individual level checks throughout
lex, parse and sema.

Saleem Abdulrasool 0e3258cea8 Preprocessor: improve ACLE 6.4.1, 6.4.2 support
This improves conformance with ACLE 6.4.1.  Define additional macros that
indicate support for the ARM and Thumb instruction set architecture.  This
includes the following set of macros:

  __ARM_ARCH
  __ARM_ARCH_ISA_ARM
  __ARM_ARCH_ISA_THUMB
  __ARM_32BIT_STATE

These help identify the environment that the code is intended to execute on.

Adjust the handling for ACLE 6.4.2 to be more correct.  We would define the
profile as a free-standing token rather than a quoted single character.

Tim Northover cadbbe1537 Atomics: emit "cmpxchg weak" where possible
Most builtins date from before the "cmpxchg weak" was a gleam in the
C++ committee's eye, so fortunately not much needs to change. But a
few of them *do* acknowledge that failure is possible.

For these, we'll emit the usual cartesian product of cmpxchg
operations if we can't statically determine weakness.  CodeGen can
sort it out later if the function gets inlined.

The only other non-trivial aspect of this is (I think) that we emit
the scalar expression for "IsWeak" once, at the beginning, and
propagate its value through the successive blocks. There's not much in
it, but it's slightly more consistent with the existing handling of
FailureOrder.

Bill Schmidt 1cf7c64fa5 [PPC64LE] Run some existing Altivec tests on powerpc64le as well
There are several Altivec tests that formerly ran only on big-endian
targets (and in some cases only on 32-bit targets).  It is useful to
verify these on little-endian targets as well.

While testing these, I discovered a typo in <altivec.h>.  This is also
fixed by this patch.

Alexey Samsonov e595e1ade0 Remove top-level Clang -fsanitize= flags for optional ASan features.
Init-order and use-after-return modes can currently be enabled
by runtime flags. use-after-scope mode is not really working at the
moment.

The only problem I see is that users won't be able to disable extra
instrumentation for init-order and use-after-scope by a top-level Clang flag.
But this instrumentation was implicitly enabled for quite a while and
we didn't hear from users hurt by it.

David Majnemer 5ef4fe7d8e MS ABI: Fix inheritance model calculation in CRTP
CRTP-like patterns involve a class which inherits from another class
using itself as a template parameter.

However, the base class itself may try to create a pointer-to-member
which involves the derived class.  This is problematic because we
may not have finished parsing the most derived classes' base specifiers
yet.

It turns out that MSVC simply uses the unspecified inheritance model
instead of doing anything fancy.

This fixes PR19987.

Reid Kleckner 32506ed8be Recover from missing 'typename' in sizeof(T::InnerType)
Summary:
'sizeof' is a UnaryExprOrTypeTrait, and it can contain either a type or
an expression.  This change threads a RecoveryTSI parameter through the
layers between TransformUnaryExprOrTypeTrait the point at which we look
up the type.  If lookup finds a single type result after instantiation,
we now build TypeSourceInfo for it just like a normal transformation
would.

This fixes the last error in the hello world ATL app that I've been
working with, and it now links and runs with clang.  Please try it and
file bugs!

Reid Kleckner a766029b81 MS ABI: Fix forming pointers to members of a base class
Previously we would calculate the inheritance model of a class when
requiring a pointer to member type of that class to be complete.  The
inheritance model is used to figure out how many fields are used by the
member pointer.

However, once we require a pointer to member of a derived class type to
be complete, we can form pointers to members of bases without
calculating the inheritance model for those bases.  This was causing
crashes on this simple test case:

  struct A {
    void f();
    void f(int);
  };
  struct B : public A {};
  void g() { void (B::*a)() = &B::f; }

Now we calculate the inheritance models of all base classes when
completing a member pointer type.

Fixes PR2007.
