Remove unused deptbl that used to contain all 32-bit edges

Summary:
We should no longer allocate the `deptbl` that kept track of all dependency hashes (as a set) in `hh_shared.c`.

Previously, this table was used to store all possible dependency edges of the 32-bit in-memory dep graph (as to not add an edge twice to the actual graph). However, since D31689793 (https://github.com/facebook/hhvm/commit/0a0368ae2478247c12249ef62b4221df87d21a19), all logic relevant to the 32-bit dep graph has been removed.
