* module/language/cps.scm ($primcall): Add "param" member, which will be
a constant parameter to the primcall. The idea is that constants used
by primcalls as immediates don't need to participate in optimizations
in any way -- they should not participate in CSE, have the same
lifetime as the primcall so not part of DCE either, and don't need
slot allocation. Indirecting them through a named $const binding is
complication for no benefit. This change should eventually improve
compilation time and memory usage, once we fully take advantage of it,
as the number of labels and variables will go down.

* module/language/cps.scm ($rec): Replace $letrec with $rec, which is an
expression, not a term. This means that the names bound by the letrec
appear twice: once in the $rec term, and once in the continuation.
This is not very elegant, but the situation is better than it was
before. Adapt all callers.
* doc/ref/compiler.texi (CPS in Guile): Incomplete documentation
updates. I'll update these later when the IL settles down.
* module/language/cps/prune-top-level-scopes.scm (compute-referenced-scopes):
Fix to not assume that scope names, continuation names, and var names
are mutually unique.
(prune-top-level-scopes): Better variable names.
* module/language/cps.scm ($kclause, $kentry): Instead of having an
entry continuation contain a list of clauses, have the clauses contain
clauses (as in Tree-IL). In some ways it's not as convenient but it
does reflect the continuation tree correctly.
