Analysis/ConstantFolding to fold ConstantExpr's, then make instcombine use it to try to use targetdata to fold constant expressions on void instructions. Also extend the icmp(inttoptr, inttoptr) folding to handle the case where int size != ptr size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51559 91177308-0d34-0410-b5e6-96231b3b80d8
