Changes: - New JitDebug class to handle all of the jit gdb interface. - Add unit tests for all, along with new offline test using debug data. - Add new Memory type called MemoryOfflineParts that has multiple MemoryOffline objects to support the offline test. - Update the tools to use the JitDebug object. - Modify libbacktrace to use the JitDebug, but only looking in libart.so and libartd.so. - Change the Format32Bits to Is32Bit since it's more accurate and I use it in a different context where original name didn't make sense. - Add a new function to find global variables in an elf file (GetGlobalVariable). - Add a new function to determine if a pc is valid for this elf (IsValidPc). Bug: 68396769 Test: Ran new unit tests. Added new offline test that uses jit debug data. Test: Ran art test that generates jit data and verified a crash unwinds Test: through the jit data.
