Raphael Isemann b69854f01c Don't take the address of an xvalue when printing an expr result
Summary:
If we have an xvalue here, we will always hit the `err_typecheck_invalid_lvalue_addrof` error
in 'Sema::CheckAddressOfOperand' when trying to take the address of the result. This patch
uses the fallback code path where we store the result in a local variable instead when we hit
this case.
