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.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Summary:
r327219 added wrappers to std::sort which randomly shuffle the container before sorting.
This will help in uncovering non-determinism caused due to undefined sorting
order of objects having the same key.
To make use of that infrastructure we need to invoke llvm::sort instead of std::sort.
Note: This patch is one of a series of patches to replace *all* std::sort to llvm::sort.
Refer the comments section in D44363 for a list of all the required patches.

parallel_for_each_n splits a given task into small pieces of tasks and then
passes them to background threads managed by a thread pool to process them
in parallel. TaskGroup then waits for all tasks to be done, which is done by
TaskGroup's destructor.
In the previous code, all tasks were passed to background threads, and the
main thread just waited for them to finish their jobs. This patch changes
the logic so that the main thread processes a task just like other
worker threads instead of just waiting for workers.
This patch improves the performance of parallel_for_each_n for a task which
is too small that we do not split it into multiple tasks. Previously, such task
was submitted to another thread and the main thread waited for its completion.
That involves multiple inter-thread synchronization which is not cheap for
small tasks. Now, such task is processed by the main thread, so no inter-thread
communication is necessary.
