Added some infrastructure for tracking and displaying information. Used
it to generate phase timing tables. Couldn't bring myself to add another
option so it's temporarily behind a system property until I sort out the
output options.

% scalac -Dscala.timings foo.scala
// or: ant -Djvm.opts="-Dscala.timings"
[...]
         phase  id    ms  share
--------------  --  ----  -----
         typer  4   5816  44.94
         mixin  20  1220  9.43
    specialize  13  1179  9.11
       erasure  15   916  7.08

...etc.  No review.
