RFR(S): 8056124 Hotspot should use PICL interface to get cacheline size on SPARC

[Igor Veresov]

Hi Morris,

Thanks for looking at it.

_L1_data_cache_line_size is a field of VM_Version (shared/vm/runtime/vm_version.hpp). It is used via it’s accessors VM_Version::L1_data_cache_line_size() in ObjectMonitor::sanity_checks() and down in ObjectSynchronizer::sanity_checks().
