* libguile/intrinsics.c (scm_to_uint64_truncate): New intrinsic.
(scm_bootstrap_intrinsics): Init new intrinsics.
* libguile/intrinsics.h: Add scm->u64, scm->u64/truncate, and scm->s64
as intrinsics, with their corresponding types.
* libguile/vm-engine.c (call-u64<-scm, call-s64<-scm): New intrinsic
calling ops.
(scm->u64, scm->s64, scm->u64/truncate): Disable opcodes.
* module/language/cps/reify-primitives.scm (compute-known-primitives):
Add intrinsics as new macroinstructions.
* module/system/vm/assembler.scm: Declare new intrinsic assemblers.
* module/language/cps/effects-analysis.scm (string-ref): Remove effects
declaration, given that the primitive is exploded now.

Add string-set!.
* libguile/vm-engine.c (string-set!): Disable opcode.
* module/language/cps/types.scm (string-ref, string-set!): Remove type
checker and inferrers for string-ref and string-set!, as both are
exploded. In the case of string-set! there are still type-check
effects in the intrinsic call but they can't be elided by the checker,
as we don't track when strings are read-only.

support for X8_S12_Z12.

helper.
(u64-=, u64-<, s64-<): Remove type checkers; this procedure does not
cause &type-check.
(u64-imm=?, s64-imm=?, u64-imm<?, imm-u64<?, s64-imm<?, imm-s64<?):
New type inferrers.
* module/language/cps/type-fold.scm (define-unary-branch-folder*): New
helper.

* libguile/throw.c (scm_throw, scm_ithrow): Adapt to not return.
* libguile/vm-engine.c (throw, throw/value, throw/value+data): New
instructions.

specialization to its own procedure, given that the bit count is
already unboxed.

instructions.

instead of an ash.
* module/language/cps/types.scm (compute-ash-range): Add type inferrers
