An overhaul of Global.

consistently, and remove things which are not being used anywhere
in the visible universe. Beyond general polish here are some of the
feature-like additions I can remember:

  * -Xshow-phases now includes descriptions of the phases.
  * -Xshow-class and -Xshow-object did not work as far as I could tell:
    if they didn't, now they do.  If they did, now they work better.
    And you don't have to give it a fully qualified name anymore.
  * -Xprint-icode will generate *.icode files (don't also have to say -Xprint:icode)
  * counts of deprecation and unchcked warnings are given
  * More documentation of what global is doing.

I tried not to break anything which might be using Global, but let me
know if I overshot somewhere. No review.
