Tobias Grosser cd95b77330 Pocc: Fix some bugs in the PoCC optimizer pass 
This includes:
  - The isl_id of the domain of the scattering must be copied from the original
    domain
  - Remove outdated references to a 'FinalRead' statement
  - Print of the Pocc output, if -debug is provided.
  - Add line breaks to some error messages.

Tobias Grosser 3cbe5cfff3 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.

Tobias Grosser 4dca439cfc Register Passes: Use -polly-optimizer=(isl|pocc) to switch optimizers 
This replaces the old option -polly-use-pocc. Also call the passes uniformly
-polly-opt-pocc and -polly-opt-isl.

This removes the separate prevector options for the Pluto and isl scheduler.

Tobias Grosser f53388034d Adapt to introduction of isl_space 
Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd
and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to
update is utils/checkout_cloog.sh.
