Subject: Revert "Refactoring attributes/types" [#3348 state:open]

This reverts commit f936a1f100e75082081e782e5cceb272885c2df7.

Conflicts:

	activerecord/lib/active_record.rb
	activerecord/lib/active_record/base.rb

Revert "Fixed: #without_typecast should only disable typecasting on the duplicated attributes" [#3387 state:open]

This reverts commit 2831996483c6a045f1f38d8030256eb58d9771c3.

Reason :

  It's not generating attribute methods properly, making object.column 5x slower.
