Require allocator parameter to YAML traits.

The allocator here can still be a nullptr, but this atleast makes the
single caller which needed nullptr be explicit about it.

Note, lld started always passing a parameter here as of r263680.  If
anything builds out of sync, that would be why errors may occur.
