Previously, some operations in `tvm.tir.op` required the operand to already be a `PrimExpr`, and raised an error if the operand was instead a python object. This could cause failures round-trip through TVMScript, as int32 and float32 types are printed as literals in TVMScript, relying on automatic conversion to convert them back into `PrimExpr` objects. For example, `T.expr2(T.int32(0))` is printed as `T.expr2(0)`, which then passes the python object `0` into `tvm.tir.op.expr2` when parsing the TVMScript. This commit updates the operations in `tvm.tir.op` to convert operands prior to accessing `operand.dtype`, avoiding the error and allowing these expressions to round-trip. This issue was first noticed in apache#15076 for `T.ret(0)`, but applied to any operator that used the operand's dtype without first normalizing to `PrimExpr`.
