Add a rather pointless InstructionSimplify transform, inspired by recent constant folding improvements: if P points to a type of size zero, turn "gep P, N" into "P". More generally, if a gep index type has size zero, instcombine could replace the index with zero, but that is not done here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119942 91177308-0d34-0410-b5e6-96231b3b80d8
