Fix FiniteDifferenceStaggeredStencilDerivation on Sympy 1.1

See merge request pycodegen/pystencils!105

Field.Access compare fails when one field access returns the offsets as ints in its hashable contents
and another one as sp.Integers.

Minor improvements to FiniteDifferenceStaggeredStencilDerivation

Fix OpenCL for CUDA OpenCL by avoid int(...) constructor

See merge request pycodegen/pystencils!102

Fix printing for Functions without name

See merge request pycodegen/pystencils!103

This fixes test for LLVM GPU using pointer_arith_func

Prefer c-style cast instead.

finite difference stencil derivation for staggered positions

Auto for assignments

See merge request pycodegen/pystencils!95

uses new Field.neighbor_vector

Reimplement create_staggered_kernel

Closes #16

See merge request pycodegen/pystencils!93

move_constants_before_loop needed to be changed to move already-existing variables up if necesesary and to preserve constness when renaming variables

Add __getnewargs__ to TypedImaginaryUnit

See merge request pycodegen/pystencils!94

Add own implementation for printing an unknown function

See merge request pycodegen/pystencils!96

also add a test for subexpressions

Using the SymPy implementation for printing a `sympy.Function` has some issues:

 - you cannot use `cast_func` as an argument -> SymPy prints
 `cast_func(2,float)
 - typed numbers are not typed any more -> e.g. pow(x, 0.25) instead of
 pow(x, 0.25f)

There was a problem when pickling TypedImaginaryUnit since it was using the __getnewargs__ of TypedSymbol.
