ART: Switch to name-based IMT hashing
Use a hash scheme based on the name. This keeps IMT slots stable
when dex tables change.
This incurs a severe performance penalty for computing the slot.
Measurements on host degraded from 30ns to an average of 85mus.
However, calls in compiled code will not incur this overhead.
Added a test comparing similar interfaces in similar dex files.
