Below there is a check:
```c++
if (CheckPointer && SeenPointer) {
const DIType *Base = DTy->getBaseType();
if (Base) {
...
```
Is it necessary to skip atomic there?
E.g. to handle situation like below:
```c
struct foo {
void * _Atomic a;
} root;
/*
$ clang -O2 -g -mcpu=v3 --target=bpf -c test4.c -o test4.o && bpftool btf dump
file test4.o
[1] STRUCT 'foo' size=8 vlen=1
'a' type_id=2 bits_offset=0
[2] PTR '(anon)' type_id=0
[3] VAR 'root' type_id=1, linkage=global
[4] DATASEC '.bss' size=0 vlen=1
type_id=3 offset=0 size=8 (VAR 'root')
*/
