Fix quickening logic

Fix varius bugs in the quickening logic where related to shared code
items for different methods.

Fixed the case where two methods quicken differently on the same code
item by checking that the quicken info is the same for all methods
that quicken the same code item. This is accomplished by requickening
and reverifying the contents of the quicken info.

Fixed the case where the dex to dex compiler would abort from a
DCHECK that there was no already quickened instructions.

Feature is tested by enabling deduping (aog/594315).

Test: test-art-host
