Fix pointer casting for i64 AtomicSMin builtin

When IGC is built with Khronos SPIRV-LLVM Translator, then builtins
mangling is not explicit, so it must be deduced based on arguments
types. In this case, pointer was casted to `int` instead of `long`
which was resulting in calling incorrect builtin function
