Tobias Grosser 29666113fd ScheduleOptimizer: Simplify some code 
We now use isl_map_equate, which makes the code a lot simpler.

Tobias Grosser 18daacad61 ScopInfo: Add parameter bounds to context 
Derive the maximal and minimal values of a parameter from the type it has. Add
this information to the scop context. This information is needed, to derive
optimal types during code generation.

Tobias Grosser 42b69e5745 ScopInfo: SCEVUnknowns are always parameters 
There is no need for special code to handle SCEVUnknowns. SCEVUnkowns are always
parameters and will be handled by the generic parameter handling code in
visit().

Tobias Grosser e71c6ab54c SCEV based code generation 
This is an incomplete implementation of the SCEV based code generation.
When finished it will remove the need for -indvars -enable-iv-rewrite.

For the moment it is still disabled. Even though it passes 'make polly-test',
there are still loose ends especially in respect of OpenMP code generation.

Tobias Grosser 84ecc47e1c 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.

Hongbin Zheng 2b4aeca74e Fix a bug introduced by r153739: We are not able to provide the correct 
dependent list for target polly-test, hence making "all" from the top
  of llvm build directory will cause the target "polly-test" being built
  before its dependencing target built.

Tobias Grosser 0905a23806 CodeGen: Recreate old ivs with the original type 
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.
