[PATCH] to Javac.java, add depend and verbose flag support

[Sean Brandt <se...@fuzzymagic.com>]

Here's a patch, that might, or might not be wanted that supports the
depend and verbose flags on javac and jikes. It also adds some support for
turning on full (+F) dependancy checking with jikes. The only caveat there
is that in order to make this effective, one has to give jikes the full
list of files to compile every time...and let it do the right thing.

Anyway, YMMV, but I'd thought I'd see if I could get these dropped in, so
I didn't have to keep maintaining local changes, and others might want
them.
