[DOCS] Remove rtl.texi references to old RTX code class names

Remove rtl.texi references to old RTX code class names

The old names were changed in svn revision
svn+ssh://gcc.gnu.org/svn/gcc/trunk@78824 138bc75d-0d04-0410-961f-82ee72b054a4
but the documentation was not fully updated at the time.

Documentation checked after full build (both .info and .pdf)
Ok for trunk?

I have no comment on the technical correctness of the patch, but spotted 
a couple markup issues:

Use @item for the first item in a group, @itemx for all the others.

Thanks for the spot, updated patch attached.

This version looks fine with me.  Nobody's made any objection about 
technical incorrectness, either, so I think it's OK to check in.

I think it's fine from the technical side as well.
