RFR (M): GRAAL-218: add CompileTheWorld functionality

[Christian Thalinger]

Here is a reworked version of the patch:

http://cr.openjdk.java.net/~twisti/GRAAL-218

There are now two different syntaxes that are supported:

1) the Hotspot way:  -XX:+CompileTheWorld -Xbootclasspath/p:foo.zip:bar.jar

2) the Graal way: -G:CompileTheWorld=foo.zip:bar.jar

The first is for compatibility and only works with optimized builds or lower (by lower I mean fastdebug, debug).  The second also works in a product build.

I've added a test which compiles the first 5 classes of rt.jar.
