This replaces the ancient INVALID/INVALID_NOVERIFY macros with a real
function.
The new invalid(..) function uses small diagnostic objects that are
generated on demand. We can store arbitrary additional information per
error type and generate useful debug/error messages on the fly.
Use it as follows:
if (/* Some error condition (ReportFoo) */)
invalid<ReportFoo>(Context, /*Assert=*/true/false,
(/* List of helpful diagnostic objects */));
Where ReportFoo is a subclass of RejectReason that is able to take the
list of helpful diagnostic objects in its constructor.
The implementation of invalid will create the report and fire
an assertion, if necessary.

During code preperation trivial PHI nodes (mainly introduced by lcssa) are
deleted to decrease the number of introduced allocas (==> dependences). However
simply replacing them by their only incoming value would cause the independent
block pass to introduce new allocas. To prevent this we try to share stack slots
during code preperarion, hence to reuse a already created alloca 'to demote' the
trivial PHI node. This works if we know that the value stored in this alloca
will be the incoming value of the trivial PHI at the end of the predecessor
block of this trivial PHI.

We explicitly specifying all filenames instead of assuming some naming
convention used by clang and opt.

For complex examples it may happen that we do not compute dependences. In this
case we do not want to crash, but just not detect parallel loops.

It does not seem to add a lot of value, as it leaves unclear which parts are
mature and whichs not. Adding this informatin also does not make sense, as it
changes rapidly.

This patch enables vectorization of loops containing backward array
traversal (array stride is -1).

This ensures that the polly passes get properly registered both, when using
polly as a loadable module and when directly linking it into clang/opt/bugpoint.

llvm.org/PR19081 reports that the polly dependence analysis causes some h264
compilation to hang. We adjust the compute out, to ensure we do not block on
expensive dependence calculations.

This reverts the broken modularized build.
This builds the classic loadable module. The separation
of library and plugin is yet to be done in a future patch.

In case we are at the innermost band, we try to prepare for vectorization. This
means, we look for the innermost parallel loop and strip mine this loop to the
innermost level using a strip-mine factor corresponding to the number of vector
iterations.
For whatever reason, the code that implemented this feature was broken. We now
added a comment, a test case and obviously also the right code.

1) The isl_int -> isl_val changes are the ones Tobias suggested.
One additional isl_val_free is added (and needed)
2) Three scoplib_vector_free are added, maybe we would need even
more (and matrix_free) but it's hard to place them right.
3) Cleaned the includes (and removed 'extern C')
This fixes the broken compilation for the scoplib import and export.

This is necessary to avoid test failures in the CLooG test suite due to the
recent isl update.
We also need to update two polly test cases which rely on a certain order in the
textual description that isl chooses for its sets and maps. Changes here are not
often, but we should probably switch to a check that verifies such maps are
semantically equivalent instead of represented identically.

Older isl versions did not properly guard all function declarations for the
use in C++. Specifically, the isl/val_gmp.h header was not properly guarded.
This patch ensures we have the proper guards in place and do not accidentally
link to name-mangled C++ versions of those functions that are not available in
libisl.so.

Value::user_iterator changes in LLVM r203364. Converts several of these
loops to nice range based loops in the process.
Built and tested cleanly for me, yay for being able to fully build and
test Polly changes!
