ebd4b17d2f Fix tridiagonalization_inplace_selector. 
The `Options` of the new `hCoeffs` vector do not necessarily match
those of the `MatrixType`, leading to build errors. Having the
`CoeffVectorType` be a template parameter relieves this restriction.

fcb5106c6e Scaled epsilon the wrong way. 
Should have been 0.5 to widen the bounds, since this is inverse
precision.  Setting to 0.5, however, leads to many more failing
tests at Google, so reverting to 1 for now.

90187a33e1 Fix SelfAdjoingEigenSolver (#2191) 
Adjust the relaxation step to use the condition
```
abs(subdiag[i]) <= epsilon * sqrt(abs(diag[i]) + abs(diag[i+1]))
```
for setting the subdiagonal entry to zero.

Also adjust Wilkinson shift for small `e = subdiag[end-1]` -
I couldn't find a reference for the original, and it was not
consistent with the Wilkinson definition.

Fixes #2191.

5f0b4a4010 Revert "Adds EIGEN_CONSTEXPR and EIGEN_NOEXCEPT to rows(), cols(), innerStride(), outerStride(), and size()" 
This reverts commit 6cbb3038ac because it
breaks clang-10 builds on x86 and aarch64 when C++11 is enabled.

f124f07965 applying EIGEN_DECLARE_TEST to *gpu* tests 
Also, a few minor fixes for GPU tests running in HIP mode.

1. Adding an include for hip/hip_runtime.h in the Macros.h file
   For HIP __host__ and __device__ are macros which are defined in hip headers.
   Their definitions need to be included before their use in the file.

2. Fixing the compile failure in TensorContractionGpu introduced by the commit to
   "Fuse computations into the Tensor contractions using output kernel"

3. Fixing a HIP/clang specific compile error by making the struct-member assignment explicit
