Looks like this got fixed along the way:

$ clang t.c -S -o - -O2 -emit-llvm
...
define i32 @main(i32 %argc, i8** nocapture %argv) nounwind readnone ssp {
entry:
  %0 = icmp eq i32 %argc, 42                      ; <i1> [#uses=1]
  %land.ext.i = zext i1 %0 to i32                 ; <i32> [#uses=1]
  ret i32 %land.ext.i
}
