Check nonlinear iv in vect_can_advance_ivs_p.
vectorizable_nonlinear_induction doesn't always guard
vect_peel_nonlinear_iv_init when it's called by
vect_update_ivs_after_vectorizer.
It's supposed to be guarded by vect_can_advance_ivs_p.
gcc/ChangeLog:
PR tree-optimization/107055
* tree-vect-loop-manip.cc (vect_can_advance_ivs_p): Check for
nonlinear induction variables.
* tree-vect-loop.cc (vect_can_peel_nonlinear_iv_p): New
functions.
(vectorizable_nonlinear_induction): Put part codes into
vect_can_peel_nonlinear_iv_p.
* tree-vectorizer.h (vect_can_peel_nonlinear_iv_p): Declare.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr107055.c: New test.
