+Clears any placeholders from a hash. If a restricted hash has any of its keys
+marked as readonly and the key is subsequently deleted, the key is not actually
+deleted but is marked by assigning it a value of &PL_sv_placeholder. This tags
+it so it will be ignored by future operations such as iterating over the hash,
+but will still allow the hash to have a value reaasigned to the key at some
+future point. This function clears any such placeholder keys from the hash.
