all missed!
Thanks to Alex Bradbury for pointing this out, and the fact that I never
added the intended `legacy` anchor to the developer policy. Add that
anchor too. With hope, this will cause the links to all resolve
successfully.

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.

This installs the new developer policy and moves all of the license
files across all LLVM projects in the monorepo to the new license
structure. The remaining projects will be moved independently.
Note that I've left odd formatting and other idiosyncracies of the
legacy license structure text alone to make the diff easier to read.
Critically, note that we do not in any case *remove* the old license
notice or terms, as that remains necessary until we finish the
relicensing process.
I've updated a few license files that refer to the LLVM license to
instead simply refer generically to whatever license the LLVM project is
under, basically trying to minimize confusion.
This is really the culmination of so many people. Chris led the
community discussions, drafted the policy update and organized the
multi-year string of meeting between lawyers across the community to
figure out the strategy. Numerous lawyers at companies in the community
spent their time figuring out initial answers, and then the Foundation's
lawyer Heather Meeker has done *so* much to help refine and get us ready
here. I could keep going on, but I just want to make sure everyone
realizes what a huge community effort this has been from the begining.

In last year's update (D48219) it was suggested that the release manager
might want to do this, so here we go.

Summary:
I originally added the -Wno-missing-braces flag because I thought it was
erroneously flagging std::array initializations. Now I realize the extra
braces really are desired for these initializations, so I'm turning the
warning flag back on.

Summary:
After experimenting with CUDA, I realized that we really only need to
set the active context right before creating an object such as a stream
or a device memory allocation. When we go on to use these objects later,
it is fine if the context that created them is no longer active,
operations with those objects will succeed anyway.
Since it turns out that we don't have to check the active context for
every operation, it makes sense to hide this active context from users
(by removing the "ActiveDeviceForThread" setter and getter) and to
change the Acxxel API to explicitly pass in the device ID to create
objects.
This change improves the Acxxel API and greatly simplifies the CUDA and
OpenCL implementations because they no longer require thread_local data.

Summary:
Acxxel is basically a simplified redesign of StreamExecutor.
Here are the major points where Acxxel differs from the current
StreamExecutor design:
* Acxxel doesn't support the kernel and kernel loader types designed for
emission by the compiler to support type-safe kernel launches. For
CUDA, kernels in Acxxel can be seamlessly launched using the standard
CUDA triple-chevron kernel launch syntax that is available with clang
and nvcc. For CUDA and OpenCL, kernel arguments can be passed in the
old-fashioned way, as one array of pointers to arguments and another
array of argument sizes. Although OpenCL doesn't get a type-safe
kernel launch method, it does still get the benefit of all the memory
management wrappers. In the future, clang may add support for
triple-chevron OpenCL kernel launchs, or some other type-safe OpenCL
kernel launch method.
* Acxxel does not depend on any other code in LLVM, so it builds
completely independently from LLVM.
The goal will be to check in Acxxel and remove StreamExecutor, or
perhaps to remove the old StreamExecutor and rename Acxxel to
StreamExecutor, so I think Acxxel should be thought of as a new version
of StreamExecutor, not as a separate project.
