Add SSE4.2 Path for CRC32, add A32 variant, add tests for non-castagnoli variants. (#1328)
* Add CRC32 A32 instructions.
* Fix CRC32 instructions.
* Add CRC intrinsic and fast path.
Loop is currently unrolled, will look into adding temp vars after tests are added.
* Begin work on Crc tests
* Fix SSE4.2 path for CRC32C, finialize tests.
* Remove unused IR path.
* Fix spacing between prefix checks.
* This should be Src.
* PTC Version
* OpCodeTable Order
* Integer check improvement. Value and Crc can be either 32 or 64 size.
* This wasn't necessary...
* If size is 3, value type must be I64.
* Fix same src+dest handling for non crc intrinsics.
* Pre-fix (ha) issue with vex encodings
