Fixes cdex which was recently changed to have shared data section, which means the DEX PC cannot be used to find the right symbol, as the bytecode is no longer within the dex file, and in-fact, we might have to scan multiple dex files to find the method. Bug: 72520014 Test: testrunner.py --host --cdex-none -t 137 Test: testrunner.py --host --cdex-fast -t 137 Test: All unit tests pass. Change-Id: I80265d05ad69dd9cefbe3f8a75e4cd349002af5e
