finite_loop_p tweak

We have finite_p flag in loop structure.  finite_loop_p already know to
use it, but we also may set the flag when we prove loop to be finite by
SCEV analysis to avoid duplicated work.

Bootstrapped/regtested x86_64-linux, OK?

gcc/ChangeLog:

* tree-ssa-loop-niter.cc (finite_loop_p): Reorder to do cheap
tests first; update finite_p flag.
