RFR: 8340808: RISC-V: Client build fails after JDK-8339738

Tue Sep 24 14:11:05 UTC 2024

Hi,
Can you help to review this simple patch?
Previously, the crc32 intrinsic (scalar version) was added for both c1/c2, then the vector version was added but depends on a global flag MaxVectorSize which is only valid in c2.
This pr is to put all vector crc32 related code under COMPILER2 macro protection.
I tested with/without --with-jvm-variants=client.
Thanks!
