EXTENDED_ARG in 3.6 fixes
...
3.6 uses EXTENDED_ARG more often appearing as the targets of jump
instructions at the beginning of line statements. All of this wreaks
havoc in the current way that our instruction processing works

Python 3.6-inspired instruction size cleanup

Revise and generalize for Python 3.6+ instructions vs < 3.6 instuctions.
Used more of the generalized methods in xdis and remove some (but not
all) of the magic numbers.
This is a lot of changes, but not all of the refactoring needed. Much
crap still remains. Also, there are still bugs in handling 3.6 bytecodes.

Correct EXTENDED_ARG handling on Python 3.6...

It possibly in other versions bug since EXTENDED_ARG is used so rarely
there because it has such a high value 1<<16, it's hard to test and

EXTENDED_ARG handling...

get_target() wasn't taking into account EXTENDED_ARG before opcode.
This is mostly relevant in Python 3.6 where the max size before needing
EXTENDED_ARG has been reduced to 256, but theoretically possible in earlier
versions.
