[pushed 1/3] gdb: remove strcmp_iw_ordered

[Simon Marchi <simon.marchi@efficios.com>]

strcmp_iw_ordered has been unused since commit b3f7f1e9d974 ("gdb:
remove psymtab.{c,h}", 2026-02-27).  Remove it.

-/* This is like strcmp except that it ignores whitespace and treats
-   '(' as the first non-NULL character in terms of ordering.  Like
-   strcmp (and unlike strcmp_iw), it returns negative if STRING1 <
-   STRING2, 0 if STRING2 = STRING2, and positive if STRING1 > STRING2
-   according to that ordering.
-
-   If a list is sorted according to this function and if you want to
-   find names in the list that match some fixed NAME according to
-   strcmp_iw(LIST_ELT, NAME), then the place to start looking is right
-   where this function would put NAME.
-
-   This function must be neutral to the CASE_SENSITIVITY setting as the user
-   may choose it during later lookup.  Therefore this function always sorts
-   primarily case-insensitively and secondarily case-sensitively.
-
-   Here are some examples of why using strcmp to sort is a bad idea:
-
-   Whitespace example:
-
-   Say your partial symtab contains: "foo<char *>", "goo".  Then, if
-   we try to do a search for "foo<char*>", strcmp will locate this
-   after "foo<char *>" and before "goo".  Then lookup_partial_symbol
-   will start looking at strings beginning with "goo", and will never
-   see the correct match of "foo<char *>".
-
-   Parenthesis example:
-
-   In practice, this is less like to be an issue, but I'll give it a
-   shot.  Let's assume that '$' is a legitimate character to occur in
-   symbols.  (Which may well even be the case on some systems.)  Then
-   say that the partial symbol table contains "foo$" and "foo(int)".
-   strcmp will put them in this order, since '$' < '('.  Now, if the
-   user searches for "foo", then strcmp will sort "foo" before "foo$".
-   Then lookup_partial_symbol will notice that strcmp_iw("foo$",
-   "foo") is false, so it won't proceed to the actual match of
-   "foo(int)" with "foo".  */
