When stepping, it's necessary to use both the unaltered relative pc and the adjusted relative pc. If the adjusted pc is not used, the wrong unwind information can be used. Added new offline unit tests that take real data and verifies that it unwinds properly. Fix a bug in the map code that would not properly parse map data for a 64 bit process when done in a 32 bit process. Fix bug in eh_frame processing that didn't adjust the pc correctly. Fix unit tests related to the pc adjustment. Bug: 69475565 Test: Passes libbacktrace/libunwindstack unit tests. Test: Run debuggerd -b on processes on a hikey.
