1) If the width of vectorization list candidate is bigger than vector reg width, we will break it down to fit the vector reg.
2) We do not vectorize the width which is not power of two.

The performance result shows it will help some spec benchmarks. mesa improved 6.97% and ammp improved 1.54%.

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.

Revert r185536 as it neither fixes any memory leaks, nor is it necessary (see the example from "man pthread_getattr_np")

ASan, LSan, MSan: try to find llvm-symbolizer binary in PATH if it is not provided. Now we don't need to explicitly set the location of llvm-symbolizer in lit test configs.

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.
