        <pre>When building some code with the experimental pass manager involving
coroutines, the id/alloc intrinsics were inlined into a function.  CodeGen then
tried to legalize the body which aborts on the `token` type.

Reduced test case:

```
; RUN: %llc -mtriple x86_64-unknown-linux-gnu -filetype asm -o - %s |
%FileCheck s

declare token @llvm.coro.id(i32, i8* readnone, i8* nocapture readonly, i8*)
declare i1 @llvm.coro.alloc(token)

define i1 @f(i8* %0) {
  %1 = call token @llvm.coro.id(i32 16, i8* %0, i8* null, i8* null)
  %2 = call i1 @llvm.coro.alloc(token %1)
  ret i1 %2
}
```</pre>
