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.

[subset] Fix subset_offset_array adding unused space to serializer.
ArrayOf.serialize_append allocates space for the new item, but ArrayOf.pop() does not recover the allocated space. So in the case where the revert path was entered the extra space added by serialize_append gets left in the serialization buffer. This moves the snapshot to before ArrayOf.serialize_append is called so that revert cleans up the buffer extend.

[subset] Fix wrong offset base for subsetting LigatureArray.
Offsets from LigatureArray must be relative to the beginning of the LigatureArray table.

So convert LigatureArray subsetting to use serialize_subset() instead of a manually called serialize and subset.
