In addition to this, I have adjusted the functions related to initialization using UseSHA256Intrinsics, UseSHA512Intrinsics, UseMD5Intrinsics, UseChaCha20Intrinsics, UseSHA1Intrinsics, UseAdler32Intrinsics to be under the control of the COMPILER2 macro.  And made related adjustments in VM_Version::c2_initialize().
