PR tree-optimization/110531 - Vect: avoid using uninitialized variable

slp_done_for_suggested_uf is used directly in vect_analyze_loop_2
without initialization, which is undefined behavior.  Initialize it to false
according to the discussion.

gcc/ChangeLog:
PR tree-optimization/110531
* tree-vect-loop.cc (vect_analyze_loop_1): initialize
slp_done_for_suggested_uf to false.
