DAG: propagate whether an arg is a pointer for CallingConv decisions.
The arm64_32 ABI specifies that pointers (despite being 32-bits) should be
zero-extended to 64-bits when passed in registers for efficiency reasons. This
means that the SelectionDAG needs to be able to tell the backend that an
argument was originally a pointer, which is implmented here.
Additionally, some memory intrinsics need to be declared as taking an i8*
instead of an iPTR.
There should be no CodeGen change yet, but it will be triggered when AArch64
backend support for ILP32 is added.
