Target: change member from reference to pointer
This is a preliminary step to help ease the construction of CallLoweringInfo. Changing the construction to a chained function pattern requires that the parameter be nullable. However, rather than copying the vector, save a pointer rather than the reference to permit a late binding of the arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209080 91177308-0d34-0410-b5e6-96231b3b80d8
