[Driver] Rename '-objcmt-white-list-dir-path' option to '-objcmt-whitelist-dir-path' and add an alias for now.

This re-lands commit r196876, which was reverted in r196879.

The tests have been fixed to pass on platforms with a stack alignment
larger than 4.

Update to clang side tests will land shortly.

Some things I missed when this first went in.

Warn if both result expressions of a ternary operator (? :) are the same.
Because only one of them will be executed, this warning will fire even if
the expressions have side effects.

Most users would be surprised if "isCOFF" and "isMachO" were simultaneously
true, unless they'd put the compiler in a box with a gun attached to a photon
detector.

This makes sure precisely one of the three formats is true for any triple and
simplifies some target logic based on that.

As consistency, invoke python with /usr/bin/env (like it is done in the rest of the file). Thanks to Xavier De Gaye for the patch

The docstrings were describing an older interface that has been replaced with
functions.

Also describe the performance characteristics of FindProgramByName() and
ExecuteAndWait() explaining when it's best to avoid them.

Summary:
This still misses a few important features, so there's no mention of
this style in the help message, but a few style rules are implemented.

immediately after SSE scalar fp instructions like addss or mulss.

Added patterns to select SSE scalar fp arithmetic instructions from a scalar
fp operation followed by a blend.

For example, given the following code:
  __m128 foo(__m128 A, __m128 B) {
    A[0] += B[0];
    return A;
  }

previously we generated:
  addss %xmm0, %xmm1
  movss %xmm1, %xmm0

now we generate:
  addss %xmm1, %xmm0

Add support for more filename extensions based on the list in the clang
plus JavaScript.

Also adds a -regex option so users can override defaults if they have unusual
file extensions or want to format everything in the diff.

Keeping with tradition the flag is modelled on Unix conventions, this time
matching the semantics of find(1).

Defaulting to iOS 3.0 when LLVM has to guess the version is no longer a useful
option and can give surprising results (like tail calls being disabled).

5.0 seems like a reasonable compromise as a platform that's still interesting
to some people.

Summary:
Allow predefined styles to define different options for different
languages so that one can run:
  clang-format -style=google file1.cpp file2.js

or use a single .clang-format file with "BasedOnStyle: Google" for both c++ and
JS files.

Added Google style for JavaScript with "BreakBeforeTernaryOperators" set to
false.

One unusual feature of the z architecture is that the result of a
previous load can be reused indefinitely for subsequent loads, even if
a cache-coherent store to that location is performed by another CPU.
A special serializing instruction must be used if you want to force
a load to be reattempted.

Since volatile loads are not supposed to be omitted in this way,
we should insert a serializing instruction before each such load.
The same goes for atomic loads.

The patch implements this at the IR->DAG boundary, in a similar way
to atomic fences.  It is a no-op for targets other than SystemZ.
