Port r15773 (60aa9f0) Original commit message: With >= 64 non-string instance types, I removed an optimization that allowed us to detect internalized strings with a single bit test. (https://code.google.com/p/v8/source/detail?r=15358) But that change caused a regression, so here is an improvement: Put the internalized string types in the lower 64 entries of INSTANCE_TYPE, and non-internalized string types in the next 64 entries. This way we can restore the single bit check.
