Description
Everywhere else in VM code we effectively do:
if (CountBytecodes || TraceBytecodes || StopInterpreterAt) BytecodeCounter::...
if (PrintBytecodeHistogram) BytecodeHistogram::...
But not in DO_UPDATE_INSTRUCTION_COUNT macro.
Adding these flags avoid the writes to statistics what would never be used (and those writes can even contend, afaics).
This change drops the Linux x86_64 Zero fastdebug build time from ~18m to ~17.5m.
