Add missing profman arg for compiled_method_threshold

The arg is --boot-image-sampled-method-threshold, this value
specifies how many profiles a non-hot method should be before it gets
marked as hot in the boot profile. This is useful if we want to do
things like compiling all executed methods for the boot image.
