Fixed bug with checking the kind of types.

The isLValueReferenceType function checks to see if the QualType's
canonical type is an LValue reference, and not if the QualType
itself is an LValue reference.  This caused a segfault when trying
to cast the QualType's Type to a LValueReference.  This is now
fixed by casting the result of getCanonicalType().

In addition, a test was added to isConsumableType to prevent
segfaults when a type being tested by the analysis is a reference
to a pointer or a pointer to a reference.

sizeof... a parameter pack should be an unevaluated context.

- can't think of a way to test this without generic lambda captures, but will include a test once that patch is made commit-ready.

[analyzer] Don't crash when a path goes through a 'delete' destructor call.

This was just left unimplemnted from r191381; the fix is to report this call

Clang modules: collect exports recursively

This change makes Module::buildVisibleModulesCache() collect exported modules
recursively.

While computing a set of exports, getExportedModules() iterates over the set of
imported modules and filters it.  But it does not consider the set of exports
of those modules -- it is the responsibility of the caller to do this.

Here is a certain instance of this issue.  Module::isModuleVisible says that
CoreFoundation.CFArray submodule is not visible from Cocoa.  Why?

- Cocoa imports Foundation.
- Foundation has an export restriction: "export *".
- Foundation imports CoreFoundation.  (Just the top-level module.)
- CoreFoundation exports CoreFoundation.CFArray.

To decide which modules are visible from Cocoa, we collect all exported modules
from immediate imports in Cocoa:

> visibleModulesFro(Cocoa) = exported(Foundation) + exported(CoreData) + exported(AppKit)

To find out which modules are exported, we filter imports according to
restrictions:

> exported(Foundation) = filterByModuleMapRestrictions(imports(Foundation))

Because Foundation imports CoreFoundation (not CoreFoundation.CFArray), the
CFArray submodule is considered not exported from Foundation, and is not
visible from Cocoa (according to Module::isModuleVisible).

ObjectiveC migrator. When inferring readwrite property,
do not remove the setter if its availability differs
from availability of the getter (which is now turned into
a property). Otherwise, synthesized setter will
inherit availability of the property (which is incorrect).

SanitizerArgs: add ability to filter/diagnose unsupported sanitizers.

The thread, memory, dataflow and function sanitizers are now diagnosed if
enabled explicitly on an unsupported platform.  Unsupported sanitizers which
are enabled implicitly (as part of a larger group) are silently disabled.  As a
side effect, this makes SanitizerArgs parsing toolchain-dependent (and thus
essentially reverts r188058), and moves SanitizerArgs ownership to ToolChain.
