LGTM. Thanks.

CodeGenTypeCache (CodeGenModule's base class) has member Int32Ty, so I don't think you need to call getInt32Ty here?

Applied Akira's comment: re-used cached Int32Ty type.

Would the original code produce duplicate version metadata here or is it just for overloaded functions? Would it make sense to add CHECK-NOT to make sure they are not generated twice?

The original code will duplicate the metadata here. Something like:

!opencl.ocl.version = !{!0, !0}

One per global value - function in case.

Existing check is already good enough as it checks exactly for one metadata:

// CHECK-SPIR-CL10-DAG: !opencl.ocl.version = !{[[OCL:![0-9]+]]}

It was passing with buggy code, since test contains exactly one function (i.e. global value). Now we have two global values and fix is required to pass existing check.
