Remove duplicate test in `tree-il.test'.

* test-suite/tests/tree-il.test ("partial evaluation"): Remove duplicate
  test for `(cons 0 (cons 1 (cons 2 (list 3 4 5))))'.
Fix and clarify documentation of `sorted?'.

Fixed <http://bugs.gnu.org/11262>.
Reported by Alexei Matveev <alexei.matveev@gmail.com>.

* libguile/sort.c (scm_sorted_p): Fix and clarify docstring.
* doc/ref/api-utility.texi (Sorting): Update accordingly.
bytevectors: Fix IEEE-754 endianness conversion.

Fixes <http://bugs.gnu.org/11310>.
Reported by Klaus Stehle <klaus.stehle@uni-tuebingen.de>.

* libguile/ieee-754.h: Remove.
* libguile/Makefile.am (noinst_HEADERS): Remove `ieee-754.h'.

* libguile/bytevectors.c (scm_ieee754_float, scm_ieee754_double): New
  unions.
  (float_to_foreign_endianness, float_from_foreign_endianness,
  double_to_foreign_endianness, double_from_foreign_endianness): Rewrite
  in terms of the new unions.

* test-suite/tests/bytevectors.test ("2.8 Operations on IEEE-754
  Representations")["single, little endian", "single, big endian",
  "double, little endian", "double, big endian"]: New tests.
Thank Klaus.
move (test-suite lib) to lower dir; cleans up uninstalled paths.

* check-guile.in:
* test-suite/Makefile.am:
* test-suite/test-suite/lib.scm:

* benchmark-guile.in:
* benchmark-suite/Makefile.am:
* benchmark-suite/benchmark-suite/lib.scm: Lower the lib modules in the
  source tree.  This lets us remove top_srcdir and top_builddir from the
  uninstalled paths.

* test-suite/tests/asm-to-bytecode.test:
* test-suite/tests/brainfuck.test:
* test-suite/tests/compiler.test:
* test-suite/tests/ftw.test:
* test-suite/tests/gc.test:
* test-suite/tests/match.test:
* test-suite/tests/rnrs-libraries.test:
* test-suite/tests/rnrs-test-a.scm:
* test-suite/tests/sxml.match.test: Adapt to not expect that module
  names be prefixed with "test-suite".
avoid inexact iteration count in benchmarks

* benchmark-suite/benchmarks/arithmetic.bm:
* benchmark-suite/benchmarks/r6rs-arithmetic.bm: Use #e1e7 for the
  iteration count, instead of the flonum 1e7.
modernize (benchmark-suite lib)

* benchmark-suite/benchmark-suite/lib.scm: Rewrite to be more modern,
  using parameters, records, and higher precision timers.  Since this
  file was never installed, this is an acceptable interface change.
  (run-benchmark): Run the thunk once before going into the benchmark.
  Adapt to new `report' interface.
  (report): Change to expect only one argument, a <benchmark-result>
  object.
  (print-result): Adapt.  The result is in the same format as before.
  (print-user-result): Adapt.  The result is different from before, but
  as this is just printed on stdout and not logged, there should be no
  problem.
  (calibrate-benchmark-framework): Pull initialization into a function.
add more primitives and predicates to (language tree-il primitives)

* module/language/tree-il/primitives.scm
  (*interesting-primitive-names*): Add number? and char?.  Add more
  numeric predicates.  Add character comparators.  Add throw, error, and
  scm-error.
  (*primitive-accessors*): Remove struct-vtable.  Though the vtable's
  contents may change (through redefinition), its identity does not
  change.
  (*effect-free-primitives*): Put struct-vtable, number?, and char?
  here.
  (*multiply-valued-primitives*): Instead of listing singly-valued
  primitives, list multiply-valued primitives.
  (*bailout-primitives*): New list.
  (*negatable-primitives*): New alist.
  (*bailout-primitive-table*, *multiply-valued-primitive-table*)
  (*negatable-primitive-table*): New tables.
  (singly-valued-primitive?): Adapt to
  use *multiply-valued-primitive-table*.
  (bailout-primitive?, negate-primitive): New exported procedures.
peval tests into separate file

* test-suite/tests/tree-il.test ("partial evaluation"):
* test-suite/tests/peval.test ("partial evaluation"): Separate peval
* tests.

* test-suite/Makefile.am: Adapt.
add effects

* module/language/tree-il/effects.scm: New module, for effects
  analysis.
* module/Makefile.am: Adapt.
peval uses effects analysis

* module/language/tree-il/peval.scm: Use effects analysis from (language
  tree-il effects) instead of our own constant-expression?.  Eagerly
  mark assigned lexicals as non-copyable.
minor tweaks to a peval test

* test-suite/tests/peval.test: Update mutable var test to really ensure
  that the function can't inline.
new pass: cse

* module/language/tree-il/cse.scm: New pass, some simple common
  subexpression elimination with effects analysis.

* test-suite/tests/cse.test: New test.

* test-suite/Makefile.am:
* module/Makefile.am: Adapt.
enable cse

* module/language/tree-il/optimize.scm: Enable CSE unless #:cse? #f is
  passed.

* test-suite/tests/tree-il.test: Disable CSE for one test.
disable optimizations in goops dispatch procedures

* module/oop/goops/dispatch.scm: Disable peval and cse.
better primitives support for bit operations

* module/language/tree-il/primitives.scm
  (*interesting-primitive-names*): Add lognot.
  (*effect-free-primitives*): Add ash, logand, logior, logxor, and
  lognot.
  (logior, logand): Define associative expanders.
more inlining in effects.scm

* module/language/tree-il/effects.scm (define-effects)
  (&no-effects, &all-effects-but-bailout):
  (cause, &depends-on, &causes, depends-on-effects?)
  (causes-effects?, effects-commute?): Add ham-fisted inlining.
cse hashing tweak

* module/language/tree-il/cse.scm (cse): Minor tweak to hash depth based
  on time profile of compiling peval.scm.
fix replacement of CSE with lexical-ref

* module/language/tree-il/cse.scm (cse): Fix dominator unrolling for
  lexical propagation.

* test-suite/tests/cse.test ("cse"): Add test.
slight vlist refactor

* module/ice-9/vlist.scm: Use define-inlinable instead of define-inline,
  to ensure strict argument evaluation.  There is a slight performance
  penalty, but I hope subsequent hacks make it up.
