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.
