[patch] Fix PR42771: Rename SESE parameters in all SCoPs after Graphite code gen

[Sebastian Pop]

Hi,

The attached patch fixes the order of detection/analysis/code-gen of
Graphite by first doing the SCoP detection and analysis for all the
SCoPs of the function, before starting the code generation.

As reported in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42771 this
used to pass after http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42521
was fixed: and then it started failing again after the fix for
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42732 that did renamed the
loop number of iterations in between two SCOP code generations, but
did not renamed the parameters of the SESEs.  With the attached patch
we now also rename the tree expressions in the SESE parameters.

I committed the attached patch to the Graphite branch for further
test.  I will commit to trunk after it's regstrapped and passes the
SPEC 2k6 tests.
