2) Make RTL/TREE layout less pointer driven.
For the clueless, ahem me, could you go into more detail on this?
When it comes to trees, these is normally (you guessed it) trees.
Tree can be represent much more compactly by linearizing them.
I.e. use polish notation. This also increases locality of reference.
When it comes to RTL, these are basically simple doubly-linked lists.
Using a vector would be much more compact and probably faster. Yes,
of course links are usefulr for re-arranging code, but there are
(1) Use a buffer with a gap, just like emacs uses.
(2) Each optimization pass just creates a fresh copy, like a copying
