RFR: 8314220: Configurable InlineCacheBuffer size

Mon Aug 14 13:39:59 UTC 2023

InlineCacheBuffer size is currently hardcoded to 10K.
This can lead to multiple ICBufferFull safepoints for InlineCacheBuffer cleanup and possible performance degradation.

Added experimental command line option InlineCacheBufferSize with the same default value, allowing it to be configured for performance experiments with ICBufferFull safepoints frequency.
