Reviewed by Mark Hahnenberg.
        
Removed isNonStringCellSpeculation, and made all callers use isObjectSpeculation.
        
Changed isNonStringCellOrOtherSpeculation to be isObjectOrOtherSpeculation.
        
I believe this is correct because even weird object types like JSNotAnObject end up
being "objects" from the standpoint of our typesystem. Anyway, the assumption that
"is cell but not a string" equates to "object" is an assumption that is already made
in other places in the system so there's little value in being paranoid about it.
