We fix the following formatting problems found by clang-format:
- 80 cols violations
- Obvious problems with missing or too many spaces
- multiple new lines in a row
clang-format suggests many more changes, most of them falling in the following
two categories:
1) clang-format does not at all format a piece of code nicely
2) The style that clang-format suggests does not match the style used in
Polly/LLVM
I consider differences caused by reason 1) bugs, which should be fixed by
improving clang-format. Differences due to 2) need to be investigated closer
to understand the cause of the difference and the solution that should be taken.

Recent changes in isl:
- Allow analysis of loops during code generation
This simplifies the detection of parallel loops.
- Simplify the way costumized ast printers are defined
This enables us to highlight parallel / vector loops in our debug output.
- Compile time improvements for codegen contexts that include parameters
- Various bug fixes
This update also gets us in sync for the isl 0.11 release.

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 .

Install the configured Config/config.h file, rather than the
Config/config.h.cmake and Config/Config.h.in source files.

Caught while compiling polly without cloog:
../tools/polly/lib/RegisterPasses.cpp:77: error: use of enum 'CodegenChoice' without previous declaration
llvm-svn: 168624
When polly was configured with cmake without cloog, compilation stopped with:
../tools/polly/lib/CodeGen/BlockGenerators.cpp:662: error: 'PollyVectorizerChoice' was not declared in this scope
../tools/polly/lib/CodeGen/BlockGenerators.cpp:662: error: 'VECTORIZER_FIRST_NEED_GROUPED_UNROLL' was not declared in this scope

When libgmp header files are not installed in the default /usr/include location,
configure used to fail to find the gmp headers when testing for isl/ast.h. This
patch adds the gmp include path to the compiler flags before testing for ISL.

Similar to LLVM we now follow the policy of only having LLVM-IR level tests in
the Polly test suite. Testing for miscompilation of larger programs should be
done with the llvm test suite.

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).

If the flags '-polly-report -g' are given, we print file name and line numbers
for the beginning and end of all detected scops.

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
