Tobias Grosser ca9a2913b7 Remove unused function

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.

Tobias Grosser 89339067b0 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.
