Yeah ... this, and Transforms/Scalar.h answer my original original
question about why a lot of passes are present as a single CPP. The
whole LLVM code generally abhors including class definitions through
header files unless absolutely necessary. It's taking me a little
effort to get used to that, but it should turn out to be a Good
Thing(tm) after all. But the problem is that the presence and the
significance of Scalar.h was not immediately obvious!
