Move state sentinels into TypeFeedbackVector.

Move state sentinels into TypeFeedbackVector.

These sentinels were in the wrong place, living in only tangentially related class TypeFeedbackInfo, but they codify state in the TypeFeedbackVector.

Hi Igor,
Here is that follow up, it does:

a) moves sentinels into TypeFeedbackVector where they belong,
b) Some places were still treating the vector as a Handle<FixedArray>, and I
changed them to use a Handle<TypeFeedbackVector>.

Thanks very much for the look,
--Michael
