Subject: Fix fehler99: always skip at least one node and check for (Copy)Keeps when looking... 
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=af0b60cf42e54a163d0b83dbab2874ea020bdc0d;p=libfirm

Fix fehler99: always skip at least one node and check for (Copy)Keeps when looking for the insertion point of a CopyKeep. Also do not check for Projs, they are not scheduled anymore.
