- Inline reads to the species protector - Put V8_LIKELY/V8_UNLIKELY to guide Array.prototype.{slice,splice,concat} to the fast paths - Put the Array species good path checks directly in Array.prototype.concat to avoid a couple reads of the array constructor from the native context These changes together bring a ~4-6% win on kraken-orig/stanford-crypto-pbkdf2-orig which more than makes up from the performance degradation from a recent other species-related change.
