Erich Keane c8cbdc659c [OpenACC] Implement 'loop' 'vector' clause (#112259) 
The 'vector' clause specifies the iterations to be executed in vector or
SIMD mode. There are some limitations on which associated compute
contexts may be associated with this and have arguments, but otherwise
this is a fairly unrestricted clause.

It DOES have region limits like 'gang' and 'worker'.
