Deven Desai 8fbd47052b Adding support for using Eigen in HIP kernels. 
This commit enables the use of Eigen on HIP kernels / AMD GPUs. Support has been added along the same lines as what already exists for using Eigen in CUDA kernels / NVidia GPUs.

Application code needs to explicitly define EIGEN_USE_HIP when using Eigen in HIP kernels. This is because some of the CUDA headers get picked up by default during Eigen compile (irrespective of whether or not the underlying compiler is CUDACC/NVCC, for e.g. Eigen/src/Core/arch/CUDA/Half.h). In order to maintain this behavior, the EIGEN_USE_HIP macro is used to switch to using the HIP version of those header files (see Eigen/Core and unsupported/Eigen/CXX11/Tensor)


Use the "-DEIGEN_TEST_HIP" cmake option to enable the HIP specific unit tests.

# Macro to add a test
#
# the unique mandatory parameter testname must correspond to a file
# <testname>.cpp which follows this pattern:
#
# #include "main.h"
# void test_<testname>() { ... }
#
# Depending on the contents of that file, this macro can have 2 behaviors,
# see below.
#
# The optional 2nd parameter is libraries to link to.
#
# A. Default behavior
#
# this macro adds an executable <testname> as well as a ctest test
# named <testname> too.
#
# On platforms with bash simply run:
# "ctest -V" or "ctest -V -R <testname>"
# On other platform use ctest as usual
#
# B. Multi-part behavior
#
# If the source file matches the regexp
# CALL_SUBTEST_[0-9]+|EIGEN_TEST_PART_[0-9]+
# then it is interpreted as a multi-part test. The behavior then depends on the
# CMake option EIGEN_SPLIT_LARGE_TESTS, which is ON by default.
#
# If EIGEN_SPLIT_LARGE_TESTS is OFF, the behavior is the same as in A (the multi-part
# aspect is ignored).
#
# If EIGEN_SPLIT_LARGE_TESTS is ON, the test is split into multiple executables
# test_<testname>_<N>
# where N runs from 1 to the greatest occurrence found in the source file. Each of these
# executables is built passing -DEIGEN_TEST_PART_N. This allows to split large tests
# into smaller executables.
#
# Moreover, targets <testname> are still generated, they
# have the effect of building all the parts of the test.
#
# Again, ctest -R allows to run all matching tests.
