node.h: Reduce struct size to fit with Ruby object size (five VALUEs)

Browse source 
by merging `rb_ast_body_t#line_count` and `#script_lines`.

Fortunately `line_count == RARRAY_LEN(script_lines)` was always
satisfied. When script_lines is saved, it has an array of lines, and
when not saved, it has a Fixnum that represents the old line_count.
