Summary:
Proposal and roadmap towards vector predication in LLVM.
This patch documents that
a) It is recognized that current LLVM is ill-equipped for vector predication.
b) The community is working on a solution.
c) A concrete prototype exists in the VP extension (D57504).

Add some common recipes for downstream users developing on top of the
existing git mirrors. These instructions show how to migrate local
branches to the monorepo.

Add a list of benchmarks, applications and algorithms which are under
discussion to be added to the test-suite.
The initial list includes the the benchmarks mentioned at
https://llvm.org/PR34216, missing SPEC benchmarks, some image processing
algorithms and a few others. The bug tracker only allows adding to the
discussion, not removing, commenting, adding details to individual
benchmarks.
The first proposal was to add these benchmark into the test-suite
repository, but after a discussion, adding it to llvm/docs/Proposals
seem more appropriate. One advantage is that llvm.org will have a
browsable web page with these suggestions.

This patch adds a new abstraction layer to VPlan and leverages it to model the planned
instructions that manipulate masks (AND, OR, NOT), introduced during predication.
The new VPValue and VPUser classes model how data flows into, through and out
of a VPlan, forming the vertices of a planned Def-Use graph. The new
VPInstruction class is a generic single-instruction Recipe that models a
planned instruction along with its opcode, operands and users. See
VectorizationPlan.rst for more details.

Following the request made in https://reviews.llvm.org/D32871, the
general documentation of the Vectorization Plan is hereby placed
under docs/Proposals.

This document describes the proposal to move to GitHub, and
compare the two proposals through various workflow examples,
presenting the current set of commands following by the ones
involved in each of the two proposals.
It is intended to supersede the previous "submodule proposal"
document entirely, and drive the discussion at the BoF during
the next Dev Meeting.

Given that other proposals are making their way through, it's better if we
specify what GitHub proposal this is, in case there are others that also
involve GitHub, but not sub-modules.

This document was crafted from the various (320+) emails between 2nd June and
20th July regarding the move to GitHub. It tried to consolidate every issue that
was raised and every solution that was presented to have a GitHub repository
with sub-modules.
It *does not* try to argue whether sub-modules are better or worse than any other
Git solution, nor if Git is better than any other VCS, nor if GitHub is better
than any other free code hosting service. This is just the final conclusions of
48 days and 320 emails (plus a lot of IRC discussions) on the LLVM community.
This document will be presented at the survey that the foundation will setup for
us to decide if we move to this solution or not. It reflects what was discussed
on the lists, but it's not authoritative. If something is not clear enough,
please refer to the mailing list discussions (hint: search for "GitHub").
