When the option -polly-loopfusion-greedy is set, the ScheduleOptimizer
tries to aggressively fuse any band it can and does not violate any
dependences.
As part if the implementation, the functionalty for copying a band
into an new schedule was extracted out of the ScheduleTreeRewriter.
The option is passed as argv to ISL's command line option parser.
Polly's own own command line options take precedence over options passed
as `-polly-isl-arg`. For instance,
`-polly-isl-arg=--schedule-outer-coincidence` will be ignored in favor
of `-polly-opt-outer-coincidence`.

The ParallelLoopGenerator class is changed such that GNU OpenMP specific
code was removed, allowing to use it as super class in a
template-pattern. Therefore, the code has been reorganized and one may
not use the ParallelLoopGenerator directly anymore, instead specific
implementations have to be provided. These implementations contain the
library-specific code. As such, the "GOMP" (code completely taken from
the existing backend) and "KMP" variant were created.
For "check-polly" all tests that involved "GOMP": equivalents were added
that test the new functionalities, like static scheduling and different
chunk sizes. "docs/UsingPollyWithClang.rst" shows how the alternative
backend may be used.

This fixes most references to the paths:
llvm.org/svn/
llvm.org/git/
llvm.org/viewvc/
github.com/llvm-mirror/
github.com/llvm-project/
reviews.llvm.org/diffusion/
to instead point to https://github.com/llvm/llvm-project.
This is *not* a trivial substitution, because additionally, all the
checkout instructions had to be migrated to instruct users on how to
use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of
checking out various projects into various subdirectories.
I've attempted to not change any scripts here, only documentation. The
scripts will have to be addressed separately.
Additionally, I've deleted one document which appeared to be outdated
and unneeded:

Fix the following error when Sphinx generates the Polly manpage:
Warning, treated as error:
docs/Performance.rst:: WARNING: "table cell spanning" not supported

Summary:
Add a document which describes:
- GEMM performance comparison.
- An experiment that measures the compile time impact
of enabling Polly when compiling LLVM+Clang+Polly.

Use ReadTheDocs theme for Sphinx if available since it is well
maintained and used by readthedocs.org.
Differential Revision: https://reviews.llvm.org/D33387

Summary:
- `include(AddSphinxTarget)` needs to occur before checking `SPHINX_FOUND`.
- `docs-polly-html` and `docs-polly-man` are now usable again.
- Perhaps we should build docs in the CI as well?

http://polly.llvm.org/example_manual_matmul.html which illustrates individual
passes of Polly, has been ported to reStructuredText and necessary changes have
been made to the configuration files used by SPHINX to include the new source as
a part of the documentation.
