  Changed paths:
    M llvm/lib/Target/AArch64/GISel/AArch64LegalizerInfo.cpp
    A llvm/test/CodeGen/AArch64/GlobalISel/legalize-inttoptr.mir
    M llvm/test/CodeGen/AArch64/GlobalISel/select-int-ptr-casts.mir

  Log Message:
  -----------
  [AArch64][GlobalISel] Mark v2s64 -> v2p0 G_INTTOPTR as legal

Allow

```
%x:_<2 x p0> = G_INTTOPTR %y:_<2 x s64>
```

This shows up when building clang for AArch64 with GlobalISel.

Also show that we can select it.

This should match SDAG's behaviour: https://godbolt.org/z/33oqYoaYv
