* 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
special cases for free-ref/free-set!.
* module/language/cps/compile-bytecode.scm (compile-function): Make
load-f64, load-s64, and load-u64 take an immediate parameter instead
of a CPS value.
* module/language/cps/effects-analysis.scm: Remove CPS argument from
immediate load instructions.
* module/language/cps/slot-allocation.scm (compute-needs-slot): Remove
special case for load-64 etc.
* module/language/cps/specialize-numbers.scm
(specialize-u64-scm-comparison): Adapt.
* module/language/cps/specialize-primcalls.scm (specialize-primcalls):
Adapt.
* module/language/cps/types.scm (define-type-inferrer*): Also take param
argument.
(define-type-inferrer, define-predicate-inferrer): Adapt.
(define-type-inferrer/param): New helper.
(load-f64, load-s64, load-u64): Adapt inferrers to pass on value from
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.

* 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/primitives.scm (*comparisons*): Remove logtest.
* module/language/cps/type-fold.scm: Remove logtest folder.
(logbit?): Fold to logand.
* module/language/cps/types.scm (logtest): Update to be a type inferrer
and not a predicate inferrer.
* module/language/tree-il/peval.scm (peval): Transform logtest and
logbit? to (zero? (logand _ _)).

* 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/language/tree-il/compile-cps.scm (convert): Fold test of
constants directly to their branches without reifying booleans, to
simplify "and" chains early.
* module/language/cps/compile-bytecode.scm (compile-function): Add
support for heap-object? in test context.
* module/language/cps/primitives.scm (*immediate-predicates*):
(*heap-type-predicates*, *comparisons*): New sets of predicates for
which the VM has branching operations.
(heap-type-predicate?): New predicate.
(*branching-primcall-arities*): Make a hash table.
(branching-primitive?, prim-arity): Adapt
to *branching-primcall-arities* being a hash table.
* module/language/cps/type-fold.scm (heap-object?): Add folder.
* module/language/tree-il/compile-cps.scm (convert): Precede heap type
checks with a heap-object? guard.
* 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
to represent the values, but it frees up bits for other purposes,
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.
(local-type-fold): Adapt scalar-value for &special-immediate change.
Delegate branch on $values to a primcall to `false?'.
This will allow heap-object? / inum? predicates to do something useful.
* module/language/cps/types.scm (&fixnum, &bignum): Split &exact-integer
into these types. Keep &exact-integer as a union type.
(type<=?): New helper.
(constant-type): Return &fixnum or &bignum as appropriate.
(define-exact-integer!): New helper, tries to make exact integer
results be &fixnum if they are within range. Adapt users.
(restricted-comparison-ranges, define-binary-result!): Use type<=?
instead of = for &exact-integer.
* module/language/cps/type-fold.scm (logtest, mul, logbit?): Use
type<=?.
* module/language/cps/specialize-numbers.scm (inferred-sigbits):
(specialize-operations): Use type<=?.
* module/language/js-il/compile-javascript.scm
(compile-jump-table, bind-opt-kw-args): Keywords should not be
parsed as optional arguments when both are present.

(module_imported_variable): New procedure.
(scm_module_index_obarray, scm_module_index_uses,
scm_module_index_import_obarray): New variables.
* module/Makefile.am (SOURCES): Install runtime.js and jslink.scm
* module/language/js-il/compile-javascript.scm (compile-exp):
Compilation units take a continuation to facilitate linking.
* module/scripts/jslink.scm: New script.
