Tobias Grosser 3fdecaee2a CodeGeneration: Localize variables 
llvm-svn: 131359

Tobias Grosser abb6dcd865 CodeGeneration: Admit that we change the code. 
No need to pretend anymore that we do not update the LLVM-IR.

Tobias Grosser e91c53d2a9 CodeGeneration: No need to forget SCoP. 
As we do not delete the SCoP, there is no need to remove it from the SCoP
detection.

Tobias Grosser 678dbbf3b0 CodeGeneration: We do not preserve the PostDominatorTree

Tobias Grosser 7a16c895ac CodeGeneration: Remove -polly-codegen-only 
If we only want to optimize a single function, we should extract this function
into a separate .ll file. This simplifies the code.

Tobias Grosser 8c4cfc327b CodeGeneration: Do not delete the old version of the Scop. 
Instead of deleting the old code, keep it on the side in an if-branch. It will
either be deleted by the dead code elimination or we can use it as fallback.

Tobias Grosser 76d7c529fb CodeGeneration: Support only simple regions

Hongbin Zheng 94c5df16e2 ScopDetection: Remember the functions generated by backend in a pointer set, so we 
do not re-generate code for these functions.

Hongbin Zheng dbdebe28de Refactor: Move 'isParallelFor' from codegen backend to Dependences analysis, so other passes can also use it.

This version is equivalent to commit ba26ebece8f5be84e9bd6315611d412af797147e
in the old git repository.
