This paves the way for adding support for modeling the destructor of a
region before it is deleted. The statement "delete <expr>" now generates
this series of CFG elements:
1. <expr>
2. [B1.1]->~Foo() (Implicit destructor)
3. delete [B1.1]

For now this just handles simple comparisons of an ANDed value with zero.
The CC value provides enough information to do any comparison for a
2-bit mask, and some nonzero comparisons with more populated masks,
but that's all future work.

Implements parsing of lambdas in the UnwrappedLineParser.
This introduces the correct line breaks; the formatting of
lambda captures are still incorrect, and the braces are also
still formatted as if they were braced init lists instead of
blocks.

Summary:
I have no idea why these were there in the first place, but now they are
certainly not necessary.

Summary:
Remove DynCastMatcher, since it is pretty much the same as Matcher<T>::WrappedMatcher.
This reduces the number of template instantiations and number of symbols in the object file.

Re-commit of r189691 and r189689 now with a proper autoconf fix.
Massive simplification of how replacements and file overrides are
handled by the migrator:
* Sources and headers are all treated the same.
* All replacements for a given translation unit are stored in the same
TranslationUnitReplacements structure.
* Change tracking is updated only from main file; no need for
propagating "is tracking" flag around.
* Transform base class no longer responsible for applying replacements.
They are simply stored and main() looks after deduplication and
application.
* Renamed -yaml-only to -serialize-replacements. Same restrictions apply:
Can only request one transform. New restriction: formatting cannot also
be turned on since it's basically a transform.
* If -serialize-replacements is requested, changes to files will not be
applied on disk.
* Changed behaviour of function generating names for serialized
replacements: Only the main source file goes into the name of the file
since a file may contain changes for multiple different files.
* Updated HeaderReplacements LIT test for new serialization behaviour.
* Replaced old test that ensures replacements are not serialized if
-serialize-replacements is not provided. New version ensures changes
are made directly to all files in the translation unit.
* Updated unit tests.
* Due to major simplification of structures in FileOverrides.h, the
FileOverridesTest is quite a bit simpler now.

libpthread is weird:
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000b9b0 T pthread_cond_init@@GLIBC_2.3.2
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000c720 T pthread_cond_init@GLIBC_2.2.5
let's do it with @@ for now
we can always introduce more macros parameters later

Select condition shadow was being ignored resulting in false negatives.
This change OR-s sign-extended condition shadow into the result shadow.

This changes the SelectionDAG nodes from ISD::INTRINSIC_W_CHAIN to
ISD::INTRINSIC_WO_CHAIN which enables easy lowering to equivalent SelectionDAG
nodes (e.g. __builtin_msa_sub_w -> ISD::SUB) in future patches since nodes
such as ISD::SUB do not have a chain.
It also corrects an obvious mistake, namely that the subtract intrinsics were
marked as being commutative.
As per a similar change in r189106
(http://llvm.org/viewvc/llvm-project?rev=189106&view=rev) there isn’t a new
testcase in this patch since the existing tests should test the intrinsics to
the same standard and the best I can do for a testcase would be a fragile
pass/maybe test of whether memory operations can (and do) cross the intrinsic.
