[PATCH] D20407: [CodeGen][ObjC] zero-ext an i1 value to i8

Also, it seems that there are bugs in the way clang handles functions whose return types are atomic. Clang asserts when compiling the following test case:

$ cat t1.c

  _Atomic _Bool b1;
  
  _Atomic _Bool foo1() {
    return b1;
  }

$ clang -std=c11 -o - -S t1.c -emit-llvm
