- Removed initializers for Optional<> fields, they are not problematic
- Remove ctor from Position, initialize on per-field basis instead.

This revision is now accepted and ready to land.
Yup, I got bitten recently from some of our plain-c-style structs with no
default initializers (in Index).
Definitely a fan of this change. Main downside is you can't use aggregate

It's not always safe, as primitive types are sometimes left uninitialized (e.g.

I think it's useful to explicit initialize non-trivial types like
`FileChangeType`. But I think it's safe and probably easier to rely on default
values of primitive types like int, bool etc. Explicitly setting default values
is probably fine (so this change LGTM), but do

This commit makes potential UB less likely. Logical errors (i.e. forgot to
initialize some fields) will still be there.
Sending this for review to make sure everyone agrees this is a good thing.

Some of the existing structs had primimtive fields that were
not explicitly initialized on construction.
After this commit every struct consistently sets
