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.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.

9061e992d5 add support for "external" depth first iterators, which store the 'visited' set
outside of the iterator itself.

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.

5ef6ffd6c3 * Spell "necessary" correctly
* Print floating point values using C99 hexadecimal style FP if possible.
  This increases the number of floating point constants that may be emitted
  inline, and improves precision for global variable initializers which
  can not be emitted in integer form.

This fixes the Olden/Power benchmark with the CBE!!!!

9860e77110 * Be TBAA safe
* Fix isFPCSafeToPrint to find more constants safe to print, which it was
  failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
  time.  This has the advantage of allowing us to emit constants at global
  scope instead of function scope.  This speeds FP programs quite a bit.

b3dab903c5 Greatly expand documentation comment at head of file... I had to
try to understand it; maybe this will help someone else do so too.
Default CVSRootDir to $CVSROOT first, then the path in ~vadve only if $CVSROOT
 was not set.
Checkout with -z3 if we might be checking out over ssh/rsh.
Check the filename of gnuplot to see if it is executable; if not, as a
 last resort, try just plain "gnuplot", hoping it is in the path somewhere.
Remove a little extra whitespace.

in it, or a space, or something, in my last build, and this seemed
like the obvious fix.)
