Tobias Grosser 64b95123ef Delete trivial PHI nodes (aka stack slot sharing) ... During code preperation trivial PHI nodes (mainly introduced by lcssa) are deleted to decrease the number of introduced allocas (==> dependences). However simply replacing them by their only incoming value would cause the independent block pass to introduce new allocas. To prevent this we try to share stack slots during code preperarion, hence to reuse a already created alloca 'to demote' the trivial PHI node. This works if we know that the value stored in this alloca will be the incoming value of the trivial PHI at the end of the predecessor block of this trivial PHI.
