Milestone
Scenario: Bing team needs to copy Giga bytes of data from Cosmos to Bing servers. Receiving side uses crc32 of the data to verify that the data is correctly received.
On targets where SSE4.2 is not supported, managed implementation should fall-back to a non-accelerated CRC-32C algorithm that intel uses.
This needs to be supported both on Desktop and CoreCLR.
