[cilkplus-merge] rewrite __sec_reduce* builtin handling to use <.def> infrastructure


Hi Joseph.

As you have requested, I have rewritten the __sec_reduce* builtins to use the built-in <.def> infrastructure. You mentioned that the __sec_implicit_index built-in may have to be rewritten as a keyword, provided that relevant changes are made to the specification. For now, I have left this as a builtin, but as soon as the spec is resolved, I can rewrite this particular one as a keyword.

I have cleaned up a lot of the __sec_reduce* handling as well and I even got rid of the REDUCE_* enums since we can just use the BUILT_IN_* enums.

Is this OK for the branch? I'd like to get a nod of approval before committing to the branch, as to aid in review, but if you prefer that I just commit at will, and then post a big "cilk plus array notation" patch to the list, I can do this instead. It just seems easier to fix stuff incrementally, as suggestions and fixes are piling up for both Balaji and myself.

Thanks.
Aldy

    Rewrite __sec_reduce* built-in handling to use the .def infrastructure.
