187a8e3e - [InstSimplify] Support ptrtoaddr in pointer subtraction fold (#162672)

[InstSimplify] Support ptrtoaddr in pointer subtraction fold (#162672) Add a new m_PtrToIntOrAddr() matcher which matches both ptrtoint and ptrtoaddr. Pointer arithmetic only works on the address bits, so supporting ptrtoaddr is always fine here.
