With `--target=powerpc-unknown-linux-gnu`, the union type is still being used
with `signext` (causing the IR verifier to be unhappy) for the following:
```c
typedef union __attribute__((__transparent_union__)) U {
signed _BitInt(17) x;
} U;
__attribute__((__weak__)) long f(U u) { return u.x; }
```
I think this is primarily an artifact of `_BitInt` not being properly handled
for AIX and PPC32 Linux though.
