# Use an empty profile to make non of the boot image be AOT compiled (for now).
# Note that we could use a previous profile but we will miss the opportunity to
# remove classes that are no longer in use.
# Ideally we would just generate an empty boot.art but we don't have the build
# support to separate the image from the compile code.
