Add SSE4.2 Path for CRC32, add A32 variant, add tests for non-castagnoli variants. (#1328)

Browse source 
* 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
