d5b7c47b27 Disable the leaf function optimization, which is apparently not legal on 
X86/linux.  :(  The problem is that a signal delivered while the function
is executing could clobber the functions stack.  This is a partial fix
for PR41.

50b5d71cb7 Make use of "external" depth-first iterators to avoid revisiting nodes 
multiple times.  This reduces the time to construct post-dominance sets a LOT.

4846f4b87a Extricate the "reverse" support from the depth-first iterator. This is really 
a crappy form of post-order traversal which really does not belong here.  While
we are at it, improve documentation and use a vector instead of a stack.

This improves the post dominator analysis pass by ~5%, and probably also helps
other passes as well.

3e58d9bb32 * Remove extraneous #includes 
* Fix a nasty initializer ordering bug.  Any only-CFG passes which registered
  themselves before the CFGOnlyAnalysis vector initialized got forgotten and
  thus got invalidated and recomputed.

In particular, in my compiled version of gccas, the Loop information pass was
being recomputed unnecessarily.

bb2d4de409 Checkin an improvement contributed by Bill: 
Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.
