Fix use after free in vector_size change
r277235 was a bit too mechanical and ended up introducing use
after free bugs in both loop and SLP vectorisation.

gcc/
* tree-vect-slp.c (vect_slp_bb_region): Check whether
autodetected_vector_size rather than vector_size is zero.
* tree-vect-loop.c (vect_analyze_loop): Likewise.
Set autodetected_vector_size immediately after calling
vect_analyze_loop_2. Check for a fatal error before advancing
next_size.
