OpenMP 4.5 allows to privatize non-static data members of current class
in non-static member functions. Patch adds initial parsing/semantic
analysis for data members support in 'reduction' clauses.

Functions with an explicit exception specification have their behavior
dictated by the specification. The additional /EHc behavior only comes
into play if no exception specification is given.

If we import a module that has a complete array type and one that has an
incomplete array type, the declaration found by name lookup might be the one with
the incomplete type, possibly resulting in rejects-valid.
Now, the name lookup prefers decls with a complete array types. Also,
diagnose cases when the redecl chain has array bound, different from the merge
candidate.

with a prior UsingDecl -- those should not even really be found by the lookup
here, except that we use the same lookup results for two different checks, and
the other check needs them.
This happens to work in *almost all* cases, because either the lookup results
list the UsingDecl first (and the NonTag result gets replaced by something
else) or because the problematic declaration is a function (which causes us to
use different logic to detect conflicts). This can also be triggered from a
state only reachable through modules (where the name lookup results can contain
multiple UsingDecls in the same scope).

Summary: The map modifier 'delete' is parser in c++ mode as a delete keyword, which requires special handling in the map clause parsing.

This patch causes the 3-stage build pipeline to only build a host compiler in the first stage, and to build all targets for subsequent stages. The host target is determined via the Native target specifier added in r262070.

Relands r260194 with a fix. If we have a template that transitions from
an extern template to an explicitly instantiated dllexport template, we
would add that class to the delayed exported class list without flushing
it.
For explicit instantiations, we can just flush the list of delayed
classes immediately. We don't have to worry about the bug fixed in
r260194 in this case because explicit instantiations can only occur at
file and namespace scope.
Fixes PR26490.

If the availability context is `FunctionTemplateDecl`, we should look
through it to the `FunctionDecl`. This prevents a diagnostic in the
following case:
class C __attribute__((unavailable));
template <class T> void foo(C&) __attribute__((unavailable));
This adds tests for availability in templates in many other cases, but
that was the only case that failed before this patch.
I added a feature `__has_feature(attribute_availability_in_templates)`
so users can test for this.

Summary:
The printf/scanf format checker is a little over-zealous in handling the conditional operator. This patch reduces work by not checking code-paths that are never used and reduces false positives regarding uncovered arguments, for example in the code fragment:
printf(minimal ? "%i\n" : "%i: %s\n", code, msg);

A member expression's base doesn't always have an impact on what the
member decl would evaluate to. In such a case, the base is used as a
poor man's scope qualifier.

Change "use of 'self' after it has been freed with call to [super dealloc]" to
"use of 'self' after it has been deallocated" and "use of instance variable
'_ivar' after the instance has been freed with call to [super dealloc]" to
"use of instance variable '_ivar' after 'self' has been deallocated".
llvm-svn: 261945
Referring to 'self' after a call to [super dealloc] is a use-after-free in
Objective-C because NSObject's -dealloc frees the memory pointed to by self.
This patch extends the ObjCSuperDeallocChecker to catch this error.

This reapplies "[analyzer] Make ObjCDeallocChecker path sensitive." (r261917)
with a fix for an error on some bots about specializing a template
from another namespace.
llvm-svn: 261929
Convert the ObjCDeallocChecker to be path sensitive. The primary
motivation for this change is to prevent false positives when -dealloc calls
helper invalidation methods to release instance variables, but it additionally
improves precision when -dealloc contains control flow. It also reduces the need
for pattern matching. The check for missing -dealloc methods remains AST-based.
