Vectors were being manually scalarized by the backend. Instead, let the target-independent code do all of the work. The manual scalarization was from a time before good target-independent support for scalarization in LLVM. However, this forces us to specially-handle vector loads and stores, which we can turn into PTX instructions that produce/consume multiple operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174968 91177308-0d34-0410-b5e6-96231b3b80d8
