ebb300d0b4 Modify Unary/Binary/TernaryOp evaluators to work for non-class types. 
This used to work for non-class types (e.g. raw function pointers) in
Eigen 3.3.  This was changed in commit 11f55b29 to optimize the
evaluator:

> `sizeof((A-B).cwiseAbs2())` with A,B Vector4f is now 16 bytes, instead of 48 before this optimization.

though I cannot reproduce the 16 byte result.  Both before the change
and after, with multiple compilers/versions, I always get a result of 40 bytes.

https://godbolt.org/z/MsjTc1PGe

This change modifies the code slightly to allow non-class types.  The
final generated code is identical, and the expression remains 40 bytes
for the `abs2` sample case.

Fixes #2251

This reverts commit 6cbb3038ac48cb5fe17eba4dfbf26e3e798041f1 because it
breaks clang-10 builds on x86 and aarch64 when C++11 is enabled.

09ae0e6586 Adjusted the EIGEN_DEVICE_FUNC qualifiers to make sure that: 
* they're used consistently between the declaration and the definition of a function
  * we avoid calling host only methods from host device methods.

296d24be4d bug #1381: fix sparse.diagonal() used as a rvalue. 
The problem was that is "sparse" is not const, then sparse.diagonal() must have the
LValueBit flag meaning that sparse.diagonal().coeff(i) must returns a const reference,
const Scalar&. However, sparse::coeff() cannot returns a reference for a non-existing
zero coefficient. The trick is to return a reference to a local member of
evaluator<SparseMatrix>.

11f55b2979 Optimize storage layout of Cwise* and PlainObjectBase evaluator to remove the functor or outer-stride if they are empty. 
For instance, sizeof("(A-B).cwiseAbs2()") with A,B Vector4f is now 16 bytes, instead of 48 before this optimization.
In theory, evaluators should be completely optimized away by the compiler, but this might help in some cases.

5271474b15 Remove common "noncopyable" base class from evaluator_base to get a chance to get EBO (Empty Base Optimization)

218c37beb4 bug #1286: automatically detect the available prototypes of functors passed to CwiseNullaryExpr such that functors have only to implement the operators that matters among: 
operator()()
 operator()(i)
 operator()(i,j)
Linear access is also automatically detected based on the availability of operator()(i,j).

39baff850c Add TernaryFunctors and the betainc SpecialFunction. 
TernaryFunctors and their executors allow operations on 3-tuples of inputs.
API fully implemented for Arrays and Tensors based on binary functors.

Ported the cephes betainc function (regularized incomplete beta
integral) to Eigen, with support for CPU and GPU, floats, doubles, and
half types.

Added unit tests in array.cpp and cxx11_tensor_cuda.cu


Collapsed revision
* Merged helper methods for betainc across floats and doubles.
* Added TensorGlobalFunctions with betainc().  Removed betainc() from TensorBase.
* Clean up CwiseTernaryOp checks, change igamma_helper to cephes_helper.
* betainc: merge incbcf and incbd into incbeta_cfe.  and more cleanup.
* Update TernaryOp and SpecialFunctions (betainc) based on review comments.

27f0434233 Introduce internal's UIntPtr and IntPtr types for pointer to integer conversions. 
This fixes "conversion from pointer to same-sized integral type" warnings by ICC.
Ideally, we would use the std::[u]intptr_t types all the time, but since they are C99/C++11 only,
let's be safe.
