47eac21072 Make fixed-size Matrix and Array trivially copyable after C++20 
Making them trivially copyable allows using std::memcpy() without undefined
behaviors.

Only Matrix and Array with trivially copyable DenseStorage are marked as
trivially copyable with an additional type trait.

As described in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p0848r3.html
it requires extremely verbose SFINAE to make the special member functions of
fixed-size Matrix and Array trivial, unless C++20 concepts are available to
simplify the selection of trivial special member functions given template
parameters. Therefore only make this feature available to compilers that support
C++20 P0848R3.

Fix #1855.

c4b1dd2f6b Add support for Cray, Fujitsu, and Intel ICX compilers 
The following preprocessor macros are added:

- EIGEN_COMP_CPE and EIGEN_COMP_CLANGCPE version number of the CRAY compiler if
  Eigen is compiled with the Cray C++ compiler, 0 otherwise.

- EIGEN_COMP_FCC and EIGEN_COMP_CLANGFCC version number of the FCC compiler if
  Eigen is compiled with the Fujitsu C++ compiler, 0 otherwise

- EIGEN_COMP_CLANGICC version number of the ICX compiler if Eigen is compiled
  with the Intel oneAPI C++ compiler, 0 otherwise

All three compilers (Cray, Fujitsu, Intel) offer a traditional and a Clang-based
frontend. This is distinguished by the CLANG prefix.

a4098ac676 Fix duplicate include guard *ALTIVEC_H -> *ZVECTOR_H 
Some some header guards were repeated between the `AltiVec` package and the
`ZVector` packages. This could cause a problem if (for whatever reason) someone
attempts to include headers for both architectures.

8eab7b6886 Improve exp<float>(): Don't flush denormal results +4% speedup. 
1. Speed up exp(x) by reducing the polynomial approximant from degree 7 to
degree 6. With exactly representable coefficients computed by the Sollya tool,
this still gives a maximum relative error of 1 ulp, i.e. faithfully rounded, for
arguments where exp(x) is a normalized float. This change results in a speedup
of about 4% for AVX2.


2. Extend the range where exp(x) returns a non-zero result to from ~[-88;88] to
~[-104;88] i.e. return denormalized values for large negative arguments instead
of zero. Compared to exp<double>(x) the denormalized results gradually decrease
in accuracy down to 0.033 relative error for arguments around x = -104 where
exp(x) is ~std::numeric<float>::denorm_min(). This is expected and acceptable.

c06c3e52a0 Include immintrin.h if F16C is available and vectorization is disabled 
If EIGEN_DONT_VECTORIZE is defined, immintrin.h is not included even if F16C is available. Trying to use F16C intrinsics thus fails.

This fixes issue #2395.

d0e3791b1a Fix vectorized reductions for Eigen::half 
Fixes compiler errors in expressions that look like

  Eigen::Matrix<Eigen::half, 3, 1>::Random().maxCoeff()

The error comes from the code that creates the initial value for
vectorized reductions. The fix is to specify the scalar type of the
reduction's initial value.

The cahnge is necessary for Eigen::half because unlike other types,
Eigen::half scalars cannot be implicitly created from integers.

b86e013321 Revert bit_cast to use memcpy for CUDA. 
To elide the memcpy, we need to first load the `src` value into
registers by making a local copy. This avoids the need to resort
to potential UB by using `reinterpret_cast`.

This change doesn't seem to affect CPU (at least not with gcc/clang).
With optimizations on, the copy is also elided.

45e67a6fda Use reinterpret_cast on GPU for bit_cast. 
This seems to be the recommended approach for doing type punning in
CUDA. See for example
- https://stackoverflow.com/questions/47037104/cuda-type-punning-memcpy-vs-ub-union
- https://developer.nvidia.com/blog/faster-parallel-reductions-kepler/
(the latter puns a double to an `int2`).
The issue is that for CUDA, the `memcpy` is not elided, and ends up
being an expensive operation.  We already have similar `reintepret_cast`s across
the Eigen codebase for GPU (as does TensorFlow).
