reification of no-clause functions to use new throw op.
* module/language/tree-il/compile-cps.scm (convert): Convert invocations

* module/language/tree-il/compile-cps.scm (convert): Convert "ash" on
immediates to rsh/immediate or lsh/immediate.
* module/language/cps/specialize-primcalls.scm (specialize-primcalls):
Don't restrict /imm params to encodeable immediates; specialize any
imm. Rely on reify-primitives to undo the transformation if needed.
* module/system/base/target.scm (target-max-size-t):
(target-max-size-t/scm, target-max-vector-length): New public
functions.
* module/language/cps/types.scm (type-entry-saturating-union): Remove
restriction of polymorphic types to be within max-size-t; this could
incorrectly apply constraints on numeric values.
(&max/size, &max/scm-size): Use target-max-size-t.
(*max-size-t*): Remove; replace uses with (target-max-size-t).
* module/language/cps/optimize.scm (optimize-first-order-cps): Move up
the simplify-primcalls pass, to allow DCE to take away unneeded
constants. An incremental step

to re-reify constant arguments for primcalls with immediate parameters
that can't be encoded as bytecode.

add/immediate, etc.
* module/language/cps/slot-allocation.scm (compute-needs-slot):
Simplify.

Rework for add/immediate, etc.
* module/language/cps/types.scm (define-unary-result!)
(define-binary-result!): Take types as params instead of variables, so
we can share this code with /imm variants.
(add/immediate, sub/immediate, uadd/immediate, usub/immediate)
(umul/immediate, ulsh/immediate, ursh/immediate): Update type
inferrers.
* module/language/cps/closure-conversion.scm (convert-one):
* module/language/cps/compile-bytecode.scm (compile-function):
* module/language/cps/effects-analysis.scm (define-primitive-effects*)
(expression-effects, primitive-effects): Only fall back to passing
constant table if the immediate parameter is false. Adapt closure
effects analysis.
* module/language/cps/slot-allocation.scm (compute-needs-slot): Remove

param.
* module/language/cps/utils.scm (compute-constant-values): Adapt.
* 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.

(kw-prelude): Emit new instructions in function preludes. Now all
branches are via the new instructions. Remove exports for old
branches.
* module/language/cps/compile-bytecode.scm (compile-function): Rename
the binary* helper back to binary, update uses, and remove logtest
branch as we no longer put logtest in test context.

* module/language/cps/types.scm: Add new variants of u64->scm and
s64->scm that can't be replaced by CSE's auxiliary definitions, so we
can sink unlikely allocations to side branches. This is a hack until
we can get allocation sinking working
* module/language/tree-il/compile-cps.scm (canonicalize, convert):
Simplify handling of branching primcalls so that `convert' only ever
sees branching primcalls in a test context.
* module/system/base/types/internal.scm (heap-tags): Rename number to
heap-number.

(heap-tag-annotations): Adapt to new names.
* module/language/cps/types.scm (&special-immediate): Model all special
immediates (iflags) under this type bit. This makes type analysis
less precise on these values as we have to use ranges instead of sets

allowing us to totally model all types in Guile.
(&eof): New &special-immediate value.
(&other-heap-object): New type bit.
Adapt inferrers.
* module/language/cps/type-fold.scm
(define-special-immediate-predicate-folder): New helper, used for
iflag comparisons.

Delegate branch on $values to a primcall to `false?'.

into these types. Keep &exact-integer as a union type.
