Fix a few auto-related issues:

 * 'auto' was being rejected on abstract-declarators with trailing return
types and on typedefs with trailing return types. 'auto' is always
allowed in these cases. This was found while testing the fix for PR 9278.

 * A very poor diagnostic was being issued for auto (f() -> int): "return
type must be 'auto', not 'auto'". This is closely related to PR 9060.

resulting in the checks for functions returning arrays and functions
returning functions being missed.

[Heikki Kultala] This patch contains the ABI changes for the TCE target.

TCE target has some too strict alignment rules (that the HW really does not require, but which caused problems elsewhere) for data types and an ABI change was decided.

a scoped enumeration type to an integral or floating type,

_Block_object_dispose;  _Block_object_dispose in fact already does
this.
