Under normal circumstances, use of CR bits is disabled when running at -O0, but it is enabled by default otherwise, and if you have optnone functions, they'll still generally be generated with crbits turned on (because nothing else turns them off). FastISel can't handle most things dealing with i1 values when using CR bits, and checks for that, but was not checking the return type on functions; we can't fast-isel function calls with i1 return values either when using CR bits for boolean values. Fixes PR22664. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@233775 91177308-0d34-0410-b5e6-96231b3b80d8
