   addi r3, r3, -1
instead of
   addi r3, r3, 1

for 'sub int X, 1'.

Secondarily, this fixes several cases where we could crash given an unsigned
constant.  And fixes a couple of minor missed optimization cases, such as
xor X, ~0U -> not X

This only fails on darwin or on X86 under valgrind.

  if (x) {
    code
    ...
  } else {
    code
    ...
  }

Turn it into:

  code
  if (x) {
    ...
  } else {
    ...
  }

This reduces code size and in some common cases allows us to completely
eliminate the conditional.  This turns several if/then/else blocks in loops
into straightline code in 179.art, turning the loops into single basic blocks
(good for modsched even!).

Maybe now brg will leave me alone ;-)

should fix the stale runtime libraries problem.

1. Nothing should happen on "make all". Doc generation is quick, but we
   don't want to do it unless we're installing.
2. Correct a dependency for the *.ps files .. didn't notice this before
   because of cruft in my directory. It failed on a clean build.
