The convention is that the directory name under "src/" (i.e.
"jdk.vm.ci") corresponds to the package name of the contained sources
(i.e. "jdk.vm.ci/share/classes/jdk.vm.ci.code/src/jdk/vm/ci/code").

Following this convention, the graal sources should either be copied
to myjdk/hotspot/src/com.oracle.graal/share/classes or the graal packe
should be renamed to jdk.vm.compiler. And then there's still the
package com.oracle.nfi which would require a separate sub-dir under
hotspot/src if it wouldn't be moved into com.oracle.graal...
