assume that the old sequence numbers will work.

The sequence numbers are still deterministic, but are now a lot less
predictable for class template partial specializations in modules/PCH.

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.

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.

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.

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.

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.

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.

Add a debug checker that is useful to understand how the ExplodedGraph is
built; it can be triggered using the following command:

The way we decide which file to remove is fairly odd. I took a quick look at
maybe changing that, but it would be a more work than I want to put at this
right now, so I left pair of FIXMEs.

llvm-svn: 184766

The goal of this sugar node is to be able to look at an arbitrary
FunctionType and tell if any of the parameters were decayed from an
array or function type.  Ultimately this is necessary to implement
Microsoft's C++ name mangling scheme, which mangles decayed arrays
differently from normal pointers.

constructing a lookup table.

Previously, buildLookup would add lookup table entries for each item lexically
within the DC, and adding the first entry with a given name would trigger the
external source to add all its entries with that name. Then buildLookup would
carry on and re-add those entries all over again.

Instead, follow a simple rule: a declaration from an external source is only
ever made visible by the external source. One exception to this: since we don't
usually build a lookup table for the TU in C, and we never serialize one, we
don't expect the external source to provide lookups in the TU in C, so we build
those ones ourselves.

There's still a problem here - since we're not appropriately using the
signedness/range of the enum to chooset the encoding and emission of
enumerators, but GCC has some bugs around this too so I assume that's
not /such/ a high priority though I may get to it soon out of
completeness.
