iseq.c (rb_iseq_compile_with_option): dummy parent_iseq for the parser
The parsing of `RubyVM::InstructionSequence.compile` does not support an
outer scope currently. So it specified NULL as parent_iseq for the
parser. However, it resulted in the following false-positive warning.
```
RubyVM::InstructionSequence.compile(<<END)
o = Object.new
o #=> <compiled>:2: warning: possibly useless use of a variable in void context
END
```
This change specifies a dummy empty parent_iseq instead of NULL, which
suppresses the false positive.
