I meant that it seems that `tryRemoveAtomicType` is missing from
`BTFTypeTypeTag::completeType`, e.g. the following example drops type tag:
```
$ cat test5.c
int _Atomic __attribute__((btf_type_tag("foo"))) *root;
$ clang -c --target=bpf -g test5.c -O2 -o test5.o && bpftool btf dump file
test5.o
[1] PTR '(anon)' type_id=2
[2] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
[3] VAR 'root' type_id=1, linkage=global
[4] DATASEC '.bss' size=0 vlen=1
type_id=3 offset=0 size=8 (VAR 'root')
```
As far as I understand, expected output is:
```
[1] TYPE_TAG 'foo' type_id=3
[2] PTR '(anon)' type_id=1
[3] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
[4] VAR 'root' type_id=2, linkage=global
[5] DATASEC '.bss' size=0 vlen=1
type_id=4 offset=0 size=8 (VAR 'root')
```
