Relax the restrictions on vector of pointer types, and vector getelementptr. Previously in a vector of pointers, the pointer couldn't be any pointer type, it had to be a pointer to an integer or floating point type. This is a hassle for dragonegg because the GCC vectorizer happily produces vectors of pointers where the pointer is a pointer to a struct or whatever. Vector getelementptr was restricted to just one index, but now that vectors of pointers can have any pointer type it is more natural to allow arbitrary vector getelementptrs. There is however the issue of struct GEPs, where if each lane chose different struct fields then from that point on each lane will be working down into unrelated types. This seems like too much pain for too little gain, so when you have a vector struct index all the elements are required to be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167828 91177308-0d34-0410-b5e6-96231b3b80d8
