Add new cleanup pass:
...
// 1. PHI nodes with multiple entries for the same predecessor. GCC sometimes
// generates code that looks like this:
//
// bb7: br bool %cond1004, label %bb8, label %bb8
// bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
// which is completely illegal LLVM code. To compensate for this, we insert
// an extra basic block, and convert the code to look like this:
//
// bb7: br bool %cond1004, label %bbX, label %bb8
// bbX: br label bb8
// bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]

This peephole eliminated 9 evil casts in the health benchmark, and
completely turned the addList method around. :)
