Created infrastructure for testing icode + sett...

Created infrastructure for testing icode + settings/partest yak shaving.

See enclosed test files/run/inline-ex-handlers.scala. To compare
optimized and unoptimized icode after a given phase, all you need in a
partest source file is this:

    import scala.tools.partest.IcodeTest
    object Test extends IcodeTest {
      override def printIcodeAfterPhase = "inlineExceptionHandlers"
    }

Other things can be done, see IcodeTest.scala. Review by ureche.
