* Add optimizations related to caller/callee saved registers, thread synchronization and disable tier 0 * Refactoring * Add a config entry to enable or disable the reg load/store opt. * Remove unnecessary register state stores for calls when the callee is know * Rename IoType to VarType * Enable tier 0 while fixing some perf issues related to tier 0 * Small tweak -- Compile before adding to the cache, to avoid lags * Add required config entry
