Anastasia added a comment.
It would be good to test your `CIndex` changes in `test/Index/opencl-types.cl`.
================
Comment at: test/SemaOpenCL/intel-subgroup-avc-ext-types.cl:26
+ char4 c4, event_t e, struct st ss) {
+ intel_sub_group_avc_mce_payload_t payload_mce = 0; // No zero initializer
for mce types
+ // expected-error@-1 {{initializing 'intel_sub_group_avc_mce_payload_t' with
an expression of incompatible type 'int'}}

W/o the spec change it's really difficult to review properly. So are you
testing 2 groups of types:
1. Init by zero in `bar`?
2. Init by builtin function in `foo`?

Comment at: test/SemaOpenCL/intel-subgroup-avc-ext-types.cl:34
+ // expected-error@-1 {{initializing 'intel_sub_group_avc_mce_payload_t' with
an expression of incompatible type 'int'}}
+ intel_sub_group_avc_ime_payload_t payload_ime = b;
+ // expected-error@-1 {{initializing 'intel_sub_group_avc_ime_payload_t' with
an expression of incompatible type 'bool'}}

I am not sure it makes sense to iterate through all different types. You don't
enumerate all of them and we don't do exhaustive testing in Clang tests anyway.
I would just check integer literal and one other builtin type.
