When the GEP index is a vector of pointers, the code that calculated the size of the element started from the vector type, and not the contained pointer type. As a result, instead of looking at the data element pointed by the vector, this code used the size of the vector. This works for 32bit members (on 32bit systems), but not for other types. Added code to peel the vector type and added a test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151626 91177308-0d34-0410-b5e6-96231b3b80d8
