I think they mean:
global = global shared memory
local = shared within a thread group (GL "shared memory")
private = ???

ureg_DECL_local_temporary seems like a good match. I'd prefer to have
a separate file though.

Shared memory is the same as TEMPs, except that they are TEMPs shared
within a thread group.
