Oh, ok. For some reason I thought I was remembering that it doesn't
build on my box.

Here's the set of fixes I have now. find_many_sub_blocks needs to be run
on the destination of the orig_entry_edge, and it also appears to munge
basic block pointers, so unconverted_simple_returns now stores jump
insns. For HJ's problem I gave in and used register numbers rather than
comparing with stack_pointer_rtx etc., and converted some more code to
use df as originally suggested by Richard S.

Testing now with rth's csa patch also applied, both i686-linux and
x86_64-linux. Bootstraps complete, all languages including Go for the
i686-linux one. Ok if testing passes?
