When running opt on this following IR., opt crashes.
I am not sure whether this is a valid test case, and I am appreciate for any clarification.
llvm version 3186ca2
test.ll
```
define internal i8 @sfork() {
entry:
%call = call i8 @foo()
%fp.val = call i8 @fork()
%cmp = icmp eq i8 %call, %fp.val
br i1 %cmp, label %merge, label %catch
catch: ; preds = %entry
%spill = landingpad %exn
unreachable
merge: ; preds = %entry
%spill = landingpad %exn
unreachable
}
```

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace and instructions to reproduce the bug.
