I wanted to create //only one// FixIt to every ctor - if I move the
forEachCtorInitializer to the register part, it would warn us twice.

The getNumCtorInitializers method counts the generated initializers as well,
not just the manually written ones.
My basic problem was that the AST's methods can't really distinguish the
generated and the manually written initializers, so it's quite complicated to
find the locations what we need. I found easier & more understandable if I
start reading the tokens.

I think it's more readable if we put the FixIts to the beginning of the
expression - it's easier to check that everyting is correct & it's more obvious
what the changes are.
