// The flag CompileThresholdScaling scales compilation thresholds
// in the following way:
//
// - if CompileThresholdScaling==1.0, the default threshold values
// are used;
//
// - if CompileThresholdScaling>1.0, threshold values are scaled
// up (e.g., CompileThresholdScalingPercentage=1.2 scales up
// thresholds by a factor of 1.2X);
//
// - if CompileThresholdScaling<1.0, threshold values are scaled
// down;
//
// - if CompileThresholdScaling==0, compilation is disabled
// (equivalent to using -Xint).
//
// With tiered compilation enabled, the values of the following
// flags are changed:
//
// Tier0InvokeNotifyFreqLog, Tier0BackedgeNotifyFreqLog,
// Tier3InvocationThreshold, Tier3MinInvocationThreshold,
// Tier3CompileThreshold, Tier3BackEdgeThreshold,
// Tier2InvokeNotifyFreqLog, Tier2BackedgeNotifyFreqLog,
// Tier3InvokeNotifyFreqLog, Tier3BackedgeNotifyFreqLog,
// Tier23InlineeNotifyFreqLog, Tier4InvocationThreshold,
// Tier4MinInvocationThreshold, Tier4CompileThreshold,
// Tier4BackEdgeThreshold
//
// With tiered compilation disabled the value of CompileThreshold
// is scaled.
