iseq.h: coverage_enabled flag

* iseq.c (prepare_iseq_build): enable coverage by coverage_enabled
  option, not by parse_in_eval flag in the thread context.
* iseq.h (rb_compile_option_struct): add coverage_enabled flag.
* parse.y (yycompile0): set coverage_enabled flag if coverage
  array is made.
