tvm.error.InternalError: Check failed: (f) is false: Cannot find intrinsic declaration, possible type mismatch: llvm.exp

Environment

tvm: 0.23.dev

Steps to reproduce

import tvm
from tvm import te, topi, tir
from tvm import meta_schedule as ms


x = te.placeholder([1, 10], dtype='int16', name='x')
op_outputs = topi.fast_tanh(x)

sch = tir.Schedule(te.create_prim_func([x, op_outputs]).with_attr('target', tvm.target.Target('llvm')))
with tvm.transform.PassContext(0):
    ref_mod = tvm.build(sch.mod, target='llvm')

BTW， topi.fast_exp has a similar bug.
