Encode inline caches with missing types in the profile
Not all runtime types can be encoded in the profile. For example if the
receiver type is in a dex file which is not tracked for profiling its
type cannot be encoded.
Previously we would just skip over these types but that can lead to
encode a polymorphic inline cache when in fact it should be megamorphic.
With this CL, inline caches for which types are missing are marked in
the profile with a special bit, kIsMissingTypesEncoding.
Also, extend profman to understand text lines which specify an inline
cache with missing types.
