CodeGen: Allow Polly to do 'grouped unrolling', but no vector generation.
...
Grouped unrolling means that we unroll a loop such that the different instances
of a certain statement are scheduled right after each other, but we do
not generate any vector code. The idea here is that we can schedule the
bb vectorizer right afterwards and use it heuristics to decide when
vectorization should be performed.

To avoid overflows we still use a larger type (i64) while calculating the value
of the old ivs. However, we truncate the result to the type of the old iv when
providing it to the new code.
A corresponding test case is added to the polly test suite. Also, a failing test
case is fixed.
This fixes PR12311.

CodeGen: Allow function parameters to be rewritten in getNewValue()
...
When deriving new values for the statements of a SCoP, we assumed that parameter
values are constant within the SCoP and consquently do not need to be rewritten.
For OpenMP code generation this assumption is wrong, as such values are not
available in the OpenMP subfunction and consequently also may need to be
rewritten.
Committed with some changes.

Remove FinalRead
...
The FinalRead statement represented a virtual read that is executed after the
SCoP. It was used when we verified the correctness of a schedule by checking if
it yields the same FLOW dependences as the original code. This is only works, if
we have a final read that reads all memory at the end of the SCoP.
We now switched to just checking if a schedule does not introduce negative
dependences and also consider WAW WAR dependences. This restricts the schedules
a little bit more, but we do not have any optimizer that would calculate a more
complex schedule. Hence, for now final reads are obsolete.

This allows us to enable -enable-iv-rewrite by default and releases LLVM from
the burdon to keep that feature. This is an intermediate step. We plan to soon

Recommit "CodeGen: Maintain a valid CFG during code generation"
...
When I first tried to commit this patch, the builder pointed after generation
of a loop still into the loop body. This means that code that was supposed to
be generated after the loop was generated right into the loop body. We fixed
this by pointing the builder to the BB after the loop, as soon as code
generation of the loop body itself is finished.

CodeGen: Maintain a valid CFG during code generation
...
Before this change we built the CFG such that it was only valid after code was
fully generated. During code generation itself, it was often incomplete. After
this change always maintain a valid CFG. This will later allow us to use the
SCEVExpander during code generation. This is the first step to get rid of the
independent blocks pass.

Add a sceleton for a polyhedral dead code elimination.
...
Such a dead code elimination can remove redundant stores to arrays. It can also
eliminate calculations where the results are stored to memory but where they are
overwritten before ever being read. It may also fix bugs like:
http://llvm.org/bugs/show_bug.cgi?id=5117
This commit just adds a sceleton without any functionality.
If anybody is interested to learn about polyhedral optimizations this would be
a good task. Well definined, self contained and pretty simple. Ping me if you
want to start and you need some pointers to get going.
