    Hi, I meet a unexpected link behavior.

I have four bitcode files: a.bc, b.bc, c.bc, d.bc.
All of them had defined three structures which are listed below.
```
%struct.atomic_t = type { i32 }
%struct.kuid_t = type { i32 }
%struct.inode = type { i16, i16, %struct.kuid_t, /*...*/ }
```
Then, using llvm-link to link them
```
llvm-link a.bc b.bc c.bc d.bc -S -o out.ll
```
```
%struct.inode = type { i16, i16, %struct.atomic_t, /*...*/ }
```
`%struct.kuid_t` (and other structures which is defined as `type { i32 }`) was replaced by `%struct.atomic_t` in `%struct.inode` (or other some structures)
The incident may be caused by LTO.
I wonder how to prevent this from happening.
Thanks for your help.
