to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Originally submitted as r326323 and r326324.
Reverted in r326432.
Reverting the commit was a mistake.
The breakage was due to invalid build files in our internal buildsystem,
CMakeLists did not have any cyclic dependencies.

Also revert "[analyzer] Fix a compiler warning"
This reverts commits r326323 and r326324.
Reason: the commits introduced a cyclic dependency in the build graph.
This happens to work with cmake, but breaks out internal integrate.

The aim of this patch is to be minimal to enable incremental development of
the feature on the top of the tree. This patch should be an NFC when the
feature is turned off. It is turned off by default and still considered as
experimental.
Technical details are available in the EuroLLVM Talk:
http://llvm.org/devmtg/2017-03//2017/02/20/accepted-sessions.html#7
Note that the initial prototype was done by A. Sidorin et al.: http://lists.llvm.org/pipermail/cfe-dev/2015-October/045730.html
Contributions to the measurements and the new version of the code: Peter Szecsi, Zoltan Gera, Daniel Krupp, Kareem Khazem.

This commit improves compatibility with the perl version of scan-build.
The perl version of scan-build produces output report directories with
increasing lexicographic ordering. This ordering is relied on by the CmpRuns.py
tool in utils/analyzer when comparing results for build commands with multiple
steps. That tool tries to line up the output directory for each step between
different runs of the analyzer based on the increasing directory name.
The python version of scan-build uses file.mkdtemp() with a time stamp
prefix to create report directories. The timestamp has a 1-second precision.
This means that when analysis of a single build step takes less than a second
the ordering property that CmpRuns.py expects will sometimes not hold,
depending on the timing and the random suffix generated by mkdtemp(). Ultimately
this causes CmpRuns to incorrectly correlate results from build steps and report
spurious differences between runs.
This commit increases the precision of the timestamp used in scan-build-py to
the microsecond level. This approach still has the same underlying issue -- but
in practice analysis of any build step is unlikely to take less than a
millisecond.

Makes scan-build successfully accept non-existing output directories provided via "-o" option. The directory is created in this case. This behavior is conforming to the old perl scan-build implementation.
