Useless sourceline in DTrace parse__begin and parse__end probes
Description
I am not 100% sure, but isn't the 'parser->parser_ruby_sourceline' at https://github.com/ruby/ruby/blob/trunk/parse.y#L5322 always '1'? Does it make sense to pass this information to DTrace parse__begin(const char *, int) and parse__end(const char *, int) probes?

It can be other than 1 if the line number is given to eval.

I think we don't pass 1 when no line information. 0 or -1 is better. and need to be documented when such special line number is happen.

May be it could be worth of own issue?

Just FYI, this is the output I get testing with SystemTap:
stap -e 'probe ruby.parse.begin { printf("*** file: %s line: %d\n", parsedfile, parsedline) }' -c 'ruby --disable-gems -e "eval "puts 1234", nil, "foo", 8"'¶
1234
*** file: internal:prelude line: 1
*** file: internal:enc/prelude line: 1
*** file: internal:gem_prelude line: 1
*** file: -e line: 1
*** file: foo line: 8
