[analyzer] Add a debug checker that prints Exploded Graph
Add a debug checker that is useful to understand how the ExplodedGraph is
built; it can be triggered using the following command:

 clang -cc1 -analyze -analyzer-checker=debug.ViewExplodedGraph my_program.c

[arcmt/driver] For the -ccc-arcmt-* flags, claim them when -fno-objc-arc is passed to avoid the
"argument unused during compilation" warning.

[ms-cxxabi] Use sugared types in the mangler instead of canonical types

At this point, it's clear that the MSVC mangler uses the type-as-written
instead of the canonical type, so this should bring us closer to MSVC.
The main thrust of this change is to fix the way we mangle decayed array
parameters of function pointer parameters.  With a DecayedType sugar
node, this code can now be much simpler.

Fixes PR16096.

This also fixes a separate issue that Richard spotted in review.
Because separate declarations of the same entity can be spelled and
mangled differently, MSVC always mangles the earliest declaration in an
attempt to avoid link errors.  Clang now does the same.

Change mangling of objects inside block literals.

This changes the mangling of local static variables/etc. inside blocks
to do something simple and sane.  This avoids depending on the way we mangle
blocks, which isn't really appropriate here.

John, please take a look at this to make sure the mangling I chose is sane.

[libclang/codecompletion] Make sure the top-level decl hash takes into account ImportDecls.

The top-level hash is used to determine if we need to update the global code-completion results.
ImportDecls did not affect the hash so a newly introduced ImportDecl would not trigger an update of the global results.

[NeonIntrinsicTestEmitter] Add requirement to arm neon intrinsic tests for the feature long_tests.

This will prevent the tests from running on normal make check. You will need to
actually pass in --param run_long_tests=true to LIT in order to run these.

Added arm_neon intrinsic tests.

This is a large test and thus it will only run if you pass in --param
run_long_tests=trueto LIT. This is intended so that this test can run on
buildbots and not when one runs make check.

Tweak -Wdeprecated-objc-pointer-introspection to have a subgroup for results of using -performSelectorXXX.

-performSelector: and friends return a value that is boxed as an Objective-C
pointer.  Sometimes it is an Objective-C pointer, sometimes it isn't.
Some clients may wish to silence this warning based on calling
this method.
