[Bug middle-end/39568] New: [graphite] Remove GBB_LOOPS

[grosser at gcc dot gnu dot org]

We create an LOOPS vector for every gimple_bb in a SCoP. This is not necessary.

It is just used for the functions
gbb_loop_index and gbb_loop_at_index

As the order of the LOOPS vector never changes (all transformations are made
using the scattering functions) it can be replaced in 
gbb_loop_index with a simple call to sese_loop_depth
gbb_loop_at_index can be implemented in the style of sese_loop_depth.
