[Attributor] AAPointerInfo mistreats ptrtoaddr as pointer-preserving cast

reproducer:
```llvm
; opt -passes=attributor %s
define void @foo() {
entry:
%0 = alloca i8
%1 = ptrtoaddr ptr %0 to i64
br label %exit
exit:
phi i64 [ %1, %entry ]
ret void
}
```

backtrace:
```
opt: /usr/workspace/moyasarda1/gpu-kernel-versioning/llvm-project-testing/llvm/include/llvm/Support/Casting.h:572: decltype(auto) llvm::cast(From *) [To = llvm::PointerType, From = llvm::Type]: Assertion `isa(Val) && "cast() argument of incompatible type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.

```

Start in llvm/lib/Transforms/IPO/AttributorAttributes.cpp, at AAPointerInfoFloating::updateImpl around the reported line 1679, and inspect how the Attributor handles ptrtoaddr uses. Run opt -passes=attributor on the supplied reproducer. Done means the reproducer no longer triggers the incompatible PointerType cast or crashes.
