[vect] Disable vectorization of epilogues for loops with SIMDUID set

gcc/ChangeLog:
2019-11-08  Andre Vieira  <andre.simoesdiasvieira@arm.com>

* tree-vect-loop.c (vect_analyze_loop): Disable epilogue vectorization
for loops with SIMDUID set.  Enable epilogue vectorization for loops
with SIMDLEN set after finding a main loop with a VF that matches it.
