[OpenACC][NFCI] Add AST Infrastructure for reduction recipes

This patch does the bare minimum to start setting up the reduction
recipe support, including adding a type to the AST to store it. No real
additional work is done, and a bunch of static_asserts are left around
to allow us to do this properly.
