Fix Wbitwise-instead-of-logical warnings
...
`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, || is usually what you
want, so clang now warns on `|` where both arguments are of type bool.
This warning fires twice in harfbuzz. In both cases, `|` is used
intentionally, with a comment explaining this.
Slightly reorder the code a bit to make the compiler happy, and to
make it obvious even without a comment that both calls should be evaluated.
No intended behavior change.

Each subgraph pointed to by a 32 bit offset should be packed into it's own space. This adds a space property to vertices which affects the distance calculation. This effectively places the distances for all of the nodes of a 32 bit subgraph into a distinct range. Thus all of the nodes of the subgraph will be packed together.

ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space.
