Jordan Rose 54533f73a8 Eliminate CXXConstructorDecl::IsImplicitlyDefined.
This field is just IsDefaulted && !IsDeleted; in all places it's used,
a simple check for isDefaulted() is superior anyway, and we were forgetting
to set it in a few cases.

Also eliminate CXXDestructorDecl::IsImplicitlyDefined, for the same reasons.

No intended functionality change.

Richard Smith d7293d7fcb Implement C++'s restrictions on the type of an expression passed to a vararg
function: it can't be 'void' and it can't be an initializer list. We give a
hard error for these rather than treating them as undefined behavior (we can
and probably should do the same for non-POD types in C++11, but as of this
change we don't).

Slightly rework the checking of variadic arguments in a function with a format
attribute to ensure that certain kinds of format string problem (non-literal
string, too many/too few arguments, ...) don't suppress this error.

David Majnemer 1365781b5b Sema: Don't assume a nested name specifier holds a type
Sema::PerformObjectMemberConversion assumed that the Qualifier it was
given holds a type. However, the specifier could hold just a namespace.
In this case, we should ignore the qualifier and not attempt to cast to
it.

Tim Northover 0389d883fc Remove rather oddly merged logic from AArch64 commit.
We seem to have ended up with both an inlined check of permitted NEON base
types and a call to a function.

Since the outer if was (I believe) strictly weaker than the one in the
function, there's no actual user-visible behaviour change, so no tests.

Patch by Ana Pazos

- Completed implementation of instruction formats:
AdvSIMD three same
AdvSIMD modified immediate
AdvSIMD scalar pairwise

- Completed implementation of instruction classes
(some of the instructions in these classes
belong to yet unfinished instruction formats):
Vector Arithmetic
Vector Immediate
Vector Pairwise Arithmetic

- Initial implementation of instruction formats:
AdvSIMD scalar two-reg misc
AdvSIMD scalar three same

- Intial implementation of instruction class:
Scalar Arithmetic

- Initial clang changes to support arm v8 intrinsics.
Note: no clang changes for scalar intrinsics function name mangling yet.

- Comprehensive test cases for added instructions
To verify auto codegen, encoding, decoding, diagnosis, intrinsics.

David Majnemer a4f7c7a600 Sema: Diagnose explicitly bound unresolved member expressions decaying into pointers to function type
We would disallow the case where the overloaded member expression is
coming from an address-of operator but we wouldn't issue any diagnostics
when the overloaded member expression comes by way of a function to
pointer decay cast.

Clang's implementation of DR61 is now seemingly complete.

Reid Kleckner a09e44c75d Fix declaring class template methods with an attributed typedef
This change unifies the logic for template instantiation of methods and
functions declared with typedefs.

It ensures that SubstFunctionType() always fills the Params out param
with non-null ParmVarDecls or returns null.

Craig Topper baca389e28 Return ExprError if both arguments to the mask form of __builtin_shufflvector don't have the same number of elements or the mask isn't an integer vector.

Eli Friedman ab09187553 Partially revert r186903.
It turns out that Plum Hall depends on us not emitting an error on
integer literals which fit into long long, but fit into
unsigned long long.  So C99 conformance requires not conforming to C99. :)

Richard Smith 0e5d7b8c6b When we perform dependent name lookup during template instantiation, it's not
sufficient to only consider names visible at the point of instantiation,
because that may not include names that were visible when the template was
defined. More generally, if the instantiation backtrace goes through a module
M, then every declaration visible within M should be available to the
instantiation. Any of those declarations might be part of the interface that M
intended to export to a template that it instantiates.

The fix here has two parts:

1) If we find a non-visible declaration during name lookup during template
instantiation, check whether the declaration was visible from the defining
module of all entities on the active template instantiation stack. The defining
module is not the owning module in all cases: we look at the module in which a
template was defined, not the module in which it was first instantiated.

2) Perform pending instantiations at the end of a module, not at the end of the
translation unit. This is general goodness, since it significantly cuts down
the amount of redundant work that is performed in every TU importing a module,
and also implicitly adds the module containing the point of instantiation to
the set of modules checked for declarations in a lookup within a template
instantiation.

There's a known issue here with template instantiations performed while
building a module, if additional imports are added later on. I'll fix that
in a subsequent commit.
