Summary: Fixes PR21100 which is caused by inconsistency between the declared return type and the expected return type at the call site. The new behavior is consistent with nvcc and the NVPTXTargetLowering::getPrototype function. Test Plan: test/Codegen/NVPTX/vector-return.ll Reviewers: jholewinski Reviewed By: jholewinski Subscribers: llvm-commits, meheff, eliben, jholewinski Differential Revision: http://reviews.llvm.org/D5612 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220607 91177308-0d34-0410-b5e6-96231b3b80d8
