So unfortunately setting CTTZ and/or CTTZ_ZERO_UNDEF to LibCall results in a
crash like those:
```
LLVM ERROR: Cannot select: t3: i32 = cttz_zero_undef t2
t2: i32,ch = CopyFromReg t0, Register:i32 %0
t1: i32 = Register %0
In function: i32_nopoison
```
I'll just FIXME them for the time being, I think.
