erichkeane d47401e376 [OpenACC] Start enforcing 'device_type' clause values 
Researching in prep of doing the implementation for lowering, I found
that the source of the valid identifiers list from flang is in the
frontend.  This patch adds the same list to the frontend, but does it as
a sema diagnostic, so we still parse it as an identifier/identifier-like
thing, but then diagnose it as invalid later.
