Additional information from Ahmed:
"CRC32 intrinsics support already exists in the JVM and this is simply enabling them for SPARC. The test file is the
only shared code added/updated. The existing flag UseCRC32Intrinsics is used to enable/disable these (enabled by default
on T5/M7). Performance increases between 2x to 9x depending on the array size."
I reviewed changes and they looks good.
