compile.c: avoid duplicate mark entry for string literal Range

iseq_add_mark_object is called in iseq_set_sequence later on,
so we only need to call iseq_add_mark_object_compile_time
in iseq_peephole_optimize.  Without this change, there would've
been a duplicate entry in the long-lived iseq mark_ary.

* compile.c (iseq_peephole_optimize): avoid duplicate mark object entry
  [ruby-core:80536] [Feature #13355]
