[PowerPC] Support powerpc64le as a syntax-checking target.

This patch provides basic support for powerpc64le as an LLVM target.
However, use of this target will not actually generate little-endian
code.  Instead, use of the target will cause the correct little-endian
built-in defines to be generated, so that code that tests for
__LITTLE_ENDIAN__, for example, will be correctly parsed for
syntax-only testing.  Code generation will otherwise be the same as
powerpc64 (big-endian), for now.

The patch leaves open the possibility of creating a little-endian
PowerPC64 back end, but there is no immediate intent to create such a
thing.

The new test case variant ensures that correct built-in defines for
little-endian code are generated.

[analyzer] Fix FP warnings when binding a temporary to a local static variable

Summary:
When binding a temporary object to a static local variable, the analyzer would
complain about a dangling reference even though the temporary's lifetime should
be extended past the end of the function. This commit tries to detect these
cases and construct them in a global memory region instead of a local one.

clang-format: Add two new style options to support WebKit style.

New options:
* Break before the commas of constructor initializers and align
  the commas with the colon.
* Break before binary operators

Additionally, for styles without column limit, don't just accept
linebreaks done by the user, but instead remove 'invalid' (according
to the current style) linebreaks and add 'required' ones.
