Tobias Grosser 46c6abb306 Remove unneeded preservation and restore of ValueMap and ClastVars in GPGPU code
generation.

We don't use the exact same way to build loop body for GPGPU codegen as openmp
codegen and other transformations do currently, in which cases 'createLoop'
function is called recursively. GPGPU codegen may fail due to improper restore
of ValueMap and ClastVars .

Tobias Grosser 3eb851f370 Remove runtime tests from polly test suite

Tobias Grosser 81a1c75035 Dependences: Add support to calculate memory based dependences
Instead of calculating exact value (flow) dependences, it is also possible to
calculate memory based dependences. Sometimes memory based dependences are a lot
easier to calculate. To evaluate the benefits, we add an option to calculate
memory based dependences (use -polly-value-dependences=false).

Tobias Grosser ebe8c8cea2 Codegen: Selectively copy in array addresses for OpenMP code
The detection of values that need to be copied in to the generated OpenMP
subfunction also detects the array base addresses needed in the SCoP. Hence, it
is not necessary to unconditionally copy all the base addresses to the generated
function.

Test cases are modified to reflect this change. Arrays which are global
variables do not occur in the struct passed to the subfunction anymore. A test
case for base address copy-in is added in copy_in_array.{c,ll}.

Committed with slight modifications

Tobias Grosser 177982c478 CodeGen: Add scop-parameters to the OpenMP context
In addition to the arrays and clast variables a SCoP statement may also refer to
values defined before the SCoP or to function arguments. Detect these values and
add them to the set of values passed to the function generated for OpenMP
parallel execution of a clast.

Committed with additional test cases and some refactoring.

Tobias Grosser a17f666f99 Codegen: Copy and restore the ValueMap and ClastVars explicitly
When generating OpenMP or GPGPU code the original ValueMap and ClastVars must be
kept. We already recovered the original ClastVars by reverting the changes, but
we did not keep the content of the ValueMap. This patch keeps now an explicit
copy of both maps and restores them after generating OpenMP or GPGPU code.

This is an adapted version of a patch contributed by:

Tobias Grosser 0c55514a43 autoconf/cmake: Always require isl code generation.
This change ensures that isl is only detected if it includes code generation

avoids missing test cases in case the feature is not available.

Tobias Grosser 6c8e696618 cmake: Use suffix for shared modules instead of the one for shared libraries
On Linux there is no difference between shared modules and shared libaries, both
are '.so' files. However, on darwin only shared modules are '.so' files. Shared
libraries have the '.dynlib' suffix.

Fix test cases on darwin by expecting a shared module suffix for Polly instead
of a shared library suffix.

This fixes PR14135

At the moment we can handle such arrays only by conservatively assuming that

great if we could improve Polly/LLVM at some point, such that we can
recover the multi-dimensionality of the accesses.
