* ruby.c: introduce --enable-frozen-string-literal-debug option.
If this option is enabled, the modify error will be:
can't modify frozen String (RuntimeError) =>
can't modify frozen String, created at test.rb:3 (RuntimeError)
* iseq.h: add compile option frozen_string_literal_debug.
* compile.c: catch up this fix.
* error.c (rb_error_frozen): ditto.
* iseq.c (set_compile_option_from_hash): ditto.
* test/ruby/test_rubyoptions.rb: add a test for this fix.
