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.

Revert "Revert "Optimize IMT"" This reverts commit 88f288e3564d79d87c0cd8bb831ec5a791ba4861. Test: Includes smali tests to exercise cts failures that led to revert. These tests check that objects that don't implement any interfaces are handled properly when interface methods are invoked on them. Bug: 29188168 (for initial CL) Bug: 29778499 (reason for revert) Change-Id: I49605d53692cbec1e2622e23ff2893fc51ed4115
