Simple Cuda backend using one thread per element (#195)

Thanks-to: Jeremy Thompson

* Take into account the compute capability of the GPU

* Add the cuda/reg backend and rename cuda to cuda/ref.

Simple Cuda backend using one thread per element (#195)

Thanks-to: Jeremy Thompson

* Take into account the compute capability of the GPU

* Add the cuda/reg backend and rename cuda to cuda/ref.

- cuda/reg uses a simple approach where each element is
processed by one thread. This approach is expected to be
efficient for 1D and 2D problems, but very ineficient
as soon as the kernels start to spill, which should arise
around Q1D=4 for 3D problems.

* Compilation takes into account the deviceId

* Make style

* Remove dead code in cuda qFunctions.

* Cuda-reg specialized Restriction.

* Split the Prolongation operator into Identity/not Identity.

* Remove "#pragma unroll" until further perf investigation.

* README update

* Add a description of cuda/reg.

* Add CompositeOperator msg to CUDA backends

Benchmarking (#187)

* Add make benchmarks

* Various tweaks related to the benchmarks.

* In Makefile:
* target 'all' now builds the library, all tests and examples
* the old 'all' target is now called 'par'
* the target 'examples' will build also the MFEM and PETSc examples if
the respective library is available.

In the benchmarks/ directory:
* remove 'config.sh'
* cleanup unused stuff from 'benchmark.sh'.

* Fix postprocess scripts, convert to Python 3

* Small update in README.md

* Set benchmark cg its max, update gitignore

* Minor makefile fix

* In Makefile, add 'par' to the list of phony targets.

* In benchmarks/postprocess-table.py, sort the table by backend first.

* Small update in examples/petsc/Makefile - add a comment that
PETSC_ARCH can be undefined/empty, e.g. when using PETSc installed
through Spack.

* In Makefile, update the benchmarking targets:
* add separate targets for individual tests: `bench-petsc-bp1`,
`bench-petsc-bp3`, etc
* `make benchmarks` runs all defined benchmarks.

Update README.md to reflect the above changes.
