Thanks for the comments.

Well, I can split the patch into maybe two parts: 1) make changes
to Location, Report and tokenizer, and 2) make changes to parser
(lexer.Location elimination). But 1) won't make sense as a
standalone patch. And in fact most of the changes are in 2).

Yeah, I totally agree.
So, based on your suggestion, I created further patch. Now it's
much more massive than before (hehe).
It recuded Location argument in several expressions and statements.
For members in iterators (MoveNext() and so on), it reuses the
same Location of the corresponding iterator itself.
Total memory allocated decreased a bit: 77618 KB
Additionally, I also added the fix for bug #57047 as Hari suggested
in tokenizer, parser and Attribute class so that Attribute accepts
"nameEscaped" bool parameter which is passed from tokenizer.
I think this patch can be delayed for review after the first one.
