olivf@chromium.org c3dde4bd9d Encapsulating Type information in the CompareICStub
Encapsulate type information in a convenient wrapper instead of storing it in a naked bitfield. This especially facilitates transitioning to a new state and converting from/to the extraICState representation. Additionally cleaning up ToBooleanICStub::Types for consistency.
