Do not set `inbounds` flag on GEPs for the following pattern:
```
((sizeof(long int) < sizeof(void *) ? (base) : (char *)0) +
(((pointer) - (sizeof(long int) < sizeof(void *) ? (base) : (char *)0) +
(align_mask)) &
~(align_mask)));
```
1. Handle the pointer addition case `(char *0) + idx`
2. Handle expr `((sizeof(long int) < sizeof(void *) ? (base) : (char *)0)` in `isUnderlyingBasePointerConstantNull`.
