context is the class itself but lookups should be performed starting with the
lookup parent of the class (class and base members don't shadow types from the
surrounding context because they have not been declared yet).

Summary:
If a module was unavailable (either a missing requirement on the module
being imported, or a missing file anywhere in the top-level module (and
not dominated by an unsatisfied `requires`)), we would silently treat
inclusions as textual. This would cause all manner of crazy and
confusing errors (and would also silently "work" sometimes, making the
problem difficult to track down).
I'm really not a fan of the `M->isAvailable(getLangOpts(), getTargetInfo(),
Requirement, MissingHeader)` function; it seems to do too many things at
once, but for now I've done things in a sort of awkward way.
The changes to test/Modules/Inputs/declare-use/module.map
were necessitated because the thing that was meant to be tested there
(introduced in r197805) was predicated on silently falling back to textual
inclusion, which we no longer do.
The changes to test/Modules/Inputs/macro-reexport/module.modulemap
are just an overlooked missing header that seems to have been missing since
this code was committed (r213922), which is now caught.

Added an additional ctor that takes a NumOccurrenceFlag parameter for the
SourcePaths option. This frees applications from always having to pass at least
one source file, e.g., -list-checks.

This enables Clang to correctly handle code such as:
struct __declspec(dllexport) S {
int x = 42;
};
where it would otherwise error due to trying to generate the default
constructor before the in-class initializer for x has been parsed.

Add checkers that detect code-level localizability issues for OS X / iOS:
- A path sensitive checker that warns about uses of non-localized
NSStrings passed to UI methods expecting localized strings.
- A syntax checker that warns against not including a comment in
NSLocalizedString macros.

It is flaky due to inability to remove files with open handles. We
could paper over it with rm -f, but then the file would still be
present.
This is more evidence to me that we should roll our own 'rm'

blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables.
We have to rebuild several expression to be sure that all variables are unique.

Currently, arguments are passed via the string attribute 'command',
assuming a shell-escaped / quoted command line to extract the original
arguments. This works well enough on Unix systems, but turns out to be
problematic for Windows tools to generate.
This CL adds a new attribute 'arguments', an array of strings, which
specifies the exact command line arguments. If 'arguments' is available
in the compilation database, it is preferred to 'commands'.
Currently there is no plan to retire 'commands': there are enough
different use cases where users want to create their own mechanism for
creating compilation databases, that it doesn't make sense to force them
all to implement shell command line parsing.

file in the .pcm files. This allows a smaller set of files to be sent to a
remote build worker when building with explicit modules (for instance, module
map files need not be sent along with the corresponding precompiled modules).
This doesn't actually make the embedded files visible to header search, so
it's not useful as a packaging format for public header files.

ConsumedBlockInfo objects were move assigned, but only in a state where
the dtor was a no-op anyway. Subtle and easily could've happened in ways
that wouldn't've been safe - so this change makes it safe no matter what
state the ConsumedBlockInfo object is in.

Make the copy/move ctors protected and defaulted in the base, make the
derived classes final to avoid exposing any slicing-prone APIs.
Also, while I'm here, simplify the use of buildByrefHelpers by taking
the parameter by value instead of non-const ref. None of the callers
care aobut observing the state after the call.

We risk iterator invalidation issues if we use a DenseMap to hold the
backing storage for an APValue. Instead, BumpPtrAllocate them and
use APValue * as our DenseMap value.
Also, don't assume that MaterializedGlobalTemporaryMap won't regrow
between when we initially perform a lookup and later on when we actually
try to insert into it.
This fixes PR24289.

Protect the special members in the base class to avoid slicing, and make

public on an intermediate base which would open up the possibility of
slicing again.

The user-defined copy assignment looks like it was working around the
presence of a reference member (that probably doesn't change in the copy
assignment cases present in the program). Rather than continuing this - just
change the reference to a pointer and let all the special members be
defined implicitly.

Turns out the one place that relied on the implicit copy ctor was safe
because it created an object in a state where the dtor was a no-op, but
that's more luck that good management.
Sure up the API by defining move construction and using it, which
implicitly disallows the unreliable copy operations.

Partly addressed by r244843, but the explicit dtor in LambdaScopeInfo
was still thwarting the implicit copy ctor. This does remove the key
function from LambdaScopeInfo unfortunately, but it seems neater than
having to explicitly default any special members LambdaScopeInfo needs.
