4; This test is to verify gc.relocate can handle pointer to vector of
5; pointers (<2 x i32 addrspace(1)*> addrspace(1)* in this case).
6; The old scheme to create a gc.relocate of <2 x i32 addrspace(1)*> addrspace(1)*
7; type will fail because llvm does not support mangling vector of pointers.
8; The new scheme will create all gc.relocate to i8 addrspace(1)* type and
9; then bitcast to the correct type.
