Detailed Description

TIR builtin intrinsics.

TIR builtin intrinsics are stored as tvm:Op. They are processed in the same way as we process Ops.

It is not necessary to create a function for every Op, as we can obtain them through Op::Get.

This file contains the most commonly used intrinsics or those that have special semantics and need compiler support.
