[FEATURE REQUEST] Remove if __debug__ is False checks.

[bpleonardo]

Hi! It would be good if --remove-debug worked on the negative checks of __debug__, in that case it would just put the body of the if statement in place.

Example:
Base code:

if __debug__:
    print('if __debug__')
if __debug__ is True:
    print('if __debug__ is True')
if __debug__ is False:
    print('if __debug__ is False')
if not __debug__:
    print('if not __debug__')

Current behavior with remove_debug:

if __debug__ is False:print('if __debug__ is False')
if not __debug__:print('if not __debug__')

Requested behavior with remove_debug:

print('if __debug__ is False')
print('if not __debug__')
