Andy Wingo d238566d0e CPS compiler reduces eq? on constant to eq-constant?
* module/language/cps/compile-bytecode.scm (compile-function): Expect
  eq-constant? instead of eq-null?, etc.
* module/language/cps/effects-analysis.scm: Likewise.
* module/language/cps/reify-primitives.scm (reify-primitives): For
  eq-constant?, reify a $const unless the constant is an immediate whose
  encoding fits in 16 bits.
* module/language/cps/type-fold.scm (materialize-constant): Helper to
  make a constant from a type, min, and max.
  (fold-eq-constant?): New helper.
  (eq-constant?): New folder.
  (undefined?): Define specifically.
  (define-nullish-predicate-folder): Renamd from
  define-special-immediate-predicate-folder.  Use only for null?, false,
  and nil?.
  (*branch-reducers*): New mechanism.  Reduce eq? to eq-constant? if
  possible.
  (local-type-fold): Refactor to use materialize-constant, and to allow
  reducing branches.
* module/language/cps/types.scm (constant-type): Return three values
  instead of a type entry.
  (constant-type-entry): New function that returns a type entry.  Adapt
  callers.
  (infer-constant-comparison): New helper.
  (eq-constant?): New inferrer.
  (undefined?): New inferrer.
* module/language/tree-il/compile-bytecode.scm (eq-constant?): Fix
  truncate-bits signed arg.
  (define-immediate-type-predicate): Adapt to visit-immediate-tags
  change.
* module/language/tree-il/compile-cps.scm (convert): Convert eq? to
  constant to eq-constant?.  Advantaged is that it gets fixnums and
  chars in addition to special immediates.
* module/language/tree-il/cps-primitives.scm (define-immediate-type-predicate):
  Adapt to allow #f as pred.
* module/system/base/types/internal.scm (immediate-tags): Use #f as pred
  for false, nil, etc.
  (immediate-bits->scm): Adapt.
* module/system/vm/assembler.scm (emit-eq-null?, emit-eq-nil?)
  (emit-eq-false?, emit-eq-true?, emit-unspecified?, emit-eof-object?):
  Remove specialized emitters.
* module/system/vm/assembler.scm (define-immediate-tag=?-macro-assembler):
  Allow for pred to be #f.
* module/system/vm/disassembler.scm (define-immediate-tag-annotation):
  Adapt to pred being #f.
