No OOM error conditions in quickfix.c and regex_nfa.c

Browse Source 
quickfix.c

 - ll_new_list
 - ll_get_or_alloc_list

regex_nfa.c

 - realloc_post_list -> EMIT -> nfa_emit_equi_class
 - nfa_regcomp_start

Use xrealloc() in realloc_post_list() (regexp_nfa.c)

  Test plan: force a call to realloc_post_list() for every use of the EMIT macro;
  open nvim and test regexp search.
