* Tidy up the treatment of SPECIALISE pragmas
Remove the now-redundant "const-dicts" field in SpecPrag
In dsBinds, abstract over constant dictionaries in the RULE.
This avoids the creation of a redundant, duplicate, rule later
in the Specialise pass, which was happening before.
There should be no effect on performance either way, just less
duplicated code, and the compiler gets a little simpler.
