Support the -i flag in the new dexdump.

Rationale:
The old dexdump supported the -i feature (ignore checksum failures).
This CL adds the same functionality to the new dexdump. Note that
this feature is, for example, useful to inspect DEX files that are
extracted from images (with quickened instructions), since the
checksum is not always valid in those cases.
