redeclaration chains when pulling in a declaration. We need the redecl chain
unless we know some other declaration will trigger it to be pulled in; that
happens if our originally-canonical declaration had all the knowledge that
we have (and isn't us).

Summary:
Without this, we would not consume the closing brace which would cause
the parser to start consuming C++ and bad things would happen.

While we previously supported __uuidof applied to a template
specialization, we would only find the uuid attribute if it was applied
to the template argument. We would erroneously ignore the uuid
attribute on the specialization itself.
This is required to parse Windows Runtime C++ Template Library headers.

Otherwise, multiple errors such as having unknown identifiers for two
arguments won't be diagnosed properly (e.g. only the first one would
have a diagnostic message if typo correction fails even though both
would be diagnosed if typo correction suggests a replacement).

array prvalue), treat that as a direct binding. Only the class prvalue case
needs to be excluded here; the rest are extensions anyway, so we can treat them

Just because we can open a directory named "COcoa.framework" doesn't

Recognize additional cases, when '::' is mistyped as ':'.
This is a fix to RP18587 - colons have too much protection in member-declarations.

This patch implements __builtin_arm_nop intrinsic for AArch32 and AArch64,
which generates hint 0x0, the alias of NOP instruction.
This intrinsic is necessary to implement ACLE __nop intrinsic.

a function pointer is neither better nor worse than binding a function lvalue
to a function rvalue reference. Don't get confused and think that both bindings
are binding to a function lvalue (which would make the lvalue form win); the
const reference is binding to an rvalue.
The "real" bug in PR20218 is still present: we're getting the wrong answer from
template argument deduction, and that's what leads us to this weird overload
set.

Previously, we would have a private backing variable and an internal
alias pointing at it.
However, -fdata-sections only fires if a global variable has non-private
linkage. This means that an unreferenced vftable wouldn't get
discarded, bloating the object file.
Instead, stick the backing variable in a comdat even if the alias has
internal linkage. This will allow the linker to drop the vftable if it
is unused.

This adds the ARM ACLE hint intrinsic wrappers to arm_acle.h. These need to be
protected with a !defined(_MSC_VER) since MSVC (and thus clang in compatibility
mode) provide these wrappers as proper builtin intrinsics.

Currently ASan instrumentation pass creates a string with global name
for each instrumented global (to include global names in the error report). Global
name is already mangled at this point, and we may not be able to demangle it
at runtime (e.g. there is no __cxa_demangle on Android).
Instead, create a string with fully qualified global name in Clang, and pass it
to ASan instrumentation pass in llvm.asan.globals metadata. If there is no metadata
for some global, ASan will use the original algorithm.
This fixes https://code.google.com/p/address-sanitizer/issues/detail?id=264.

MSVC accepts __noop without any trailing parens and treats it like a
literal zero. We don't treat __noop as an integer literal, but now at
least we can parse a naked __noop expression.

OS X TLS has all accesses going through the thread-wrapper function and
gives the backing thread-local variable internal linkage. This means
that thread-wrappers must have WeakAnyLinkage so that references to the
internal thread-local variables do not get propagated to other code.
It also means that translation units which do not provide a definition
for the thread-local variable cannot attempt to emit a thread-wrapper
because the thread wrapper will attempt to reference the backing
variable.

into their container; we won't find them there. These things are already being
merged when they're added to their primary template's folding set, so this
merging is redundant (and causes us to reject-valid because we think we've
found an odr violation).

The relevant portion of C++ standard says [namespace.memdef]p3:
If the name in a friend declaration is neither qualified nor a
template-id and the declaration is a function or an
elaborated-type-specifier, the lookup to determine whether the entity
has been previously declared shall not consider any scopes outside the
innermost enclosing namespace.
MSVC does not implement that rule for types. If there is a type in an
enclosing namespace, they consider an unqualified tag declaration with
the same name to be a redeclaration of the type from another namespace.
Implementing compatibility is a simple matter of disabling our
implementation of this rule for types, which was added in r177473.
