intel moved the repository around.
github changes the prefix inside the tar according to the
repository name.
So all sha256 have changed!
I verified that the tar contents for 2019.4 did not change
except for the prefix.
* TensorFlow: Clean up/simplify the installation, make sure the headers are
installed so that horovod can find them successfully. Fix the 2.0.* builds.
* Backport of 837c8b6b upstream

## Summary
This PR updates and improves the Spack package for [UPC++](https://upcxx.lbl.gov).
I'm an LBL employee and developer on the UPC++ team, as well as the maintainer of this Spack package.
### Key Improvements:
* Adding new 2020.3.0 release and support for use of develop/master branches
- Our build infrastructure underwent a major change in this release, switching from a hand-rolled Python2 script to a bash-based autoconf work-alike.
- The new build system is NOT using autotools (nor does it support some of the more esoteric autoconf options), but the user interface for common builds is similar.
* Add explicit support for an MPI optional dependency
- New `mpi` variant enables use of the MPI-based spawner (most relevant on loosely coupled clusters), and the (unofficial) mpi-conduit backend
- This variant is OFF by default, since UPC++ works fine without MPI on many systems, increasing the likelihood first-time Spack users get a working build without needing to correctly setup MPI
* Add support for post-install testing using the test support deployed in the new build infrastructure
* Fix or workaround a few bugs observed during testing
### Status
The new package has been validated with a variety of specs across over seven different systems, including: NERSC cori, ALCF Theta, OLCF Summit, an in-house Linux cluster, and macOS laptops (Mojave and Catalina).
Expose serial/parallel build (MPI), CUDA/OpenMP backends, Clang, and
Ascent bindings.
Interestingly, `warpx +ascent` currently leads to an infinite loop in
the Spack concretizer.
Removed provider_index use of 'import from' and refactored a few routines to a further subclassing of _IndexBase for implementing user defined bindings of provider specs.
Git-based conditions database for HEP and other experiments.
Use latest release version and current master to support Linux and
macOS. Add core known dependencies and conflicts related to C++17
support.
cxxstd variant added to help transitive dependencies, and for future
support for newer standards in future.
* relocate: removed import from statements
* relocate: renamed *Exception to *Error
This aims at consistency in naming with both
the standard library (ValueError, AttributeError,
etc.) and other errors in 'spack.error'.
Improved existing docstrings
* relocate: simplified search function by un-nesting conditionals
The search function that searches for patchelf has been
refactored to remove deeply nested conditionals.
Extended docstring.
* relocate: removed a condition specific to unit tests
* relocate: added test for _patchelf
Our unit tests run many times. Any unit test which actually installs
a package (which involves fetching code on the internet) is a severe
bug because it runs an installation many times (i.e. re-downloading
the same package for each version of Python that we run unit tests
for).
This reverts commit 25893f1, which added tests that install real
packages.
