First I forgot to commit all the files for the
Java support.  Then I spoke the wrong CVS command.
This commit just adds the log message!

--------------------------
Add support for Java generation, written in
a lightning day with Erik Meijer

	ghc -J Foo.hs

will do the business, generating Foo.java

The code is in a new directory, javaGen/, so
you'll need to cvs update -d.

I've reorganised main/CodeOutput quite a bit; it
is now much much tidier, and will accommodate new
languages quite easily.

I've also fiddled with the flags that communicate
between the driver and hsc.

GONE:	-S=  -C=

NEW:	-olang=xxx	output language xxx
			xxx can be: C, asm, java

	-ofile=xxx	put the output code in file xxx


BEWARE that I might have broken some of the more
cryptic stuff in ghc.lprl.
