Add new filed attributeOwnerIdBeforeInline to IrAttributeContainer

This field is null by default, and it is set to current
`attributeOwnerId` when declaration was inlined and must be
generated with new name. In its turn `attributeOwnerId` must be set to
`this` to show that this is actually a new declaration, not a copy.
