[patch, fortran] Final TRIM optimizations

Hello world,

this is the last round of TRIM optimizations.  This patch extends the
treatment of trailing TRIMs in concatenations to comparisions.  It also
does a bit of code cleanup by removing some duplication, and by not
changing the rhs in optimize_assignment.

OK for trunk?

         * frontend-passes.c (remove_trim):  New function.
         (optimize_assignment):  Use it.
         (optimize_comparison):  Likewise.  Return correct status
         for previous change.
