// C1/C2: count is incremented on type overflow and decremented for failed type checks
// JVMCI: count decremented for failed type checks and nonprofiled_count is incremented on type overflow
// TODO (chaeubl): in fact, JVMCI should also increment the count for failed type checks to mimic the C1/C2 behavior
// count is decremented for failed type checks
// JVMCI only: nonprofiled_count is incremented on type overflow

// C1/C2: count is incremented on type overflow
// JVMCI: count is incremented on type overflow, nonprofiled_count is incremented on method overflow
// count is incremented on type overflow
// JVMCI only: nonprofiled_count is incremented on method overflow
// JVMCI is interested in knowing the percentage of type checks involving a type not explicitly in the profile
