Subject: [tree-ssa][PATCH]: Speed up SSAPRE, start Load PRE

This patch speeds up and reduces the memory usage of SSAPRE.
On one testcase, it went from 100 seconds to 4 on my Macintosh.

It also starts to implement load PRE Load PRE on non-indirect refs now works (and bootstraps and passes regtests), but i've disabled it until i get it *all* working at once (it currently miscompiles stage2 slightly).

I fixed a few bugs along the way that others had pointed out.

We also now keep and print memory statistics.

Bootstrapped and regtested on 686-pc-linux-gnu (and powerpc-darwin-7.0.0 with a few darwin config changes). Committed. --Dan
