74032f471d Remove limit_scops
This patch removes graphite-scop-detection.c:limit_scops function and fix
related issues arising because of that. The functionality limit_scop was added
as an intermediate step to discard the loops which graphite could not
handle. Removing limit_scop required handling of different cases of loops and
surrounding code.  The scop is now larger so most test cases required 'number of
scops detected' to be fixed. By increasing the size of scop we can now optimize
loops which are 'siblings' of each other. This could enable loop fusion on a
number of loops. Since in the graphite framework we mostly want to opimize
loop-nests/adjacent-loops, we now discard scops with less than 2 loops. We
also discard scops without any data references.

Essentially:
 - Remove limite_scops.
 - Only select scops when there are at least two loops (loop nest or, side by side).
 - Discard loops without data-refs.
 - Fix test cases.

Passes bootstrap and reg-test.
