The code names above were used for AMD's FinFET technology before AMD moved to the constellation based nomenclature, as wccftech reports.
As we reported earlier this month; Polaris being the the codename of their next line of GPUs.
AMD would have sent AIDA64/ HWINFO PCI-e ID information relevant to the new GPUs, as seen from the HWINFO32/64 most recent change log:
HWiNFO32 & HWiNFO64
Changes in HWiNFO32 & HWiNFO64 v5.12 - Released on: Jan-7-2016:
Improved drive scan safety.
Improved sensor list color notification of alarms.
Enhanced support of Intel Kaby Lake.
Added monitoring of Windows Hardware Error Architecture (WHEA) errors.
Updated sensor graphs to reflect custom value formats.
Added support of direct-connected Corsair AXi/HXi series PSUs.
Added monitoring of drive/NAND lifetime reads/writes (S.M.A.R.T.).
Added monitoring of drive read/write total since last boot.
Upcoming changes in the next release:
Fixed monitoring of total/NAND reads/writes for some SanDisk drives.
Extended NVMe S.M.A.R.T. status and fixed total writes amount.
Fixed reporting of sub-zero temperatures on NVIDIA GPUs.
Added support of Samsung SSD 950 Pro using the default Microsoft NVMe driver.
Added preliminary support of AMD Ellesmere, Baffin, Greenland.
Fixed GPU I2C access on AMD Tonga/Amethyst.
Added options to choose which type of values (current, mix, max, average) to show in tray, LG LCD and RTSS.
Enhanced sensor monitoring on ASUS Z170-PREMIUM.
Download pre-release: v5.13, Build 2765
Added support of IRF IR35201.

As to which codename relates to what is under heavy speculation right now; current calculated guesses being:
Ellesmere/Baffin are each of Polaris 10 and Polaris 11.
Vega, which speculated to be previously Greenland, will be the successor(s) of Polaris 10 and Polaris 11.
The above inclusion may indicate that AMD have now entered or at least are getting ready for the testing phase of the Polaris GPU(s).
You can see the below slide from AMD covering the roadmap for GCN, namely for FinFET for 2016:
