Unreviewed patch: tree-ssa/loop-14.c test case failure

Hello,

the replacement in loop-14.c should not happen in ivopts, but
in tree-scalar-evolution.c:scev_const_prop.

Final value replacement in ivopts was never reliable and it is
redundant nowadays.  The reason I haven't removed it yet is that
I have a complete rewrite of ivopts more or less ready, but probably
I should do that anyway, to avoid confusion.
