erichkeane 009b5e8e59 [OpenACC] 'vector' clause implementation for combined constructs
Similar to 'worker', the 'vector' clause has some rules that needed to
be applied on its argument legality that for combined constructs need to
look at the current construct, not the 'effective' parent construct.
Additionally, it has some interaction with `vector_length` that needed
to be encoded as well.  This patch implements it.
