00fbdfa734 Handle GMP allocations through libgc and remove bignum finalizers. 
This significantly speeds up loads that create lots of bignums, like
(language cps slot-allocation) for files with many top-level
definitions.  Compiling such a file is typically 2.5 times faster.

See <https://lists.gnu.org/archive/html/guile-devel/2020-02/msg00023.html>.

* libguile/numbers.c (custom_gmp_malloc): Use
'scm_gc_malloc_pointerless' instead of 'scm_malloc'.
(custom_gmp_realloc): Use 'scm_gc_realloc'.
(custom_gmp_free): Remove call to 'free'.
(make_bignum): Use 'scm_gc_malloc' instead of 'scm_gc_malloc_pointerless'.
Call 'scm_i_set_finalizer' only when SCM_INSTALL_GMP_MEMORY_FUNCTIONS is
false.

a3a726c868 Optimize fixnum exact integer square roots. 
* libguile/numbers.c (scm_exact_integer_sqrt, scm_sqrt)
(exact_integer_is_perfect_square, exact_integer_floor_square_root):
Where it is trivial to do so, use GMP's low-level mpn functions to
avoid heap allocation.

00973cbd2e In 'ash' and 'round-ash', handle right shift count of LONG_MIN. 
Fixes <https://bugs.gnu.org/21901>.
Reported by Zefram <zefram@fysh.org>.

* libguile/numbers.c: Add another top-level 'verify' to ensure that
LONG_MIN is not a fixnum.
(scm_ash, scm_round_ash): Ensure that when the shift count is LONG_MIN,
it is not handled via the normal code path, to avoid signed overflow
when the shift count is negated.
* test-suite/tests/numbers.test: Add tests.

e6100f64bb Fix 'round-ash' of negative integers by huge right shift counts. 
This is a followup to commit 011aec7e24.

When rounding, right shifting a negative integer by a huge shift count
results in 0, not -1.

* libguile/numbers.c: Add top-level 'verify' to ensure that the
assumptions in 'scm_ash' and 'scm_round_ash' are valid.
(scm_round_ash): In the case that handles huge right shifts, require
that the shift count _exceeds_ the integer length, and return 0 instead
of -1.
* test-suite/tests/numbers.test: Adjust tests accordingly.

e4c5f73f94 Gracefully handle huge shift counts in 'ash' and 'round-ash'. 
Fixes <https://bugs.gnu.org/32644>.
Reported by Stefan Israelsson Tampe <stefan.itampe@gmail.com>.

The need for this arose because the type inferrer for 'ursh' sometimes
passes (- 1 (expt 2 64)) as the second argument to 'ash'.

* libguile/numbers.c (scm_ash, scm_round_ash): Gracefully handle several
cases where the shift count does not fit in a C 'long'.
* test-suite/tests/numbers.test: Add tests.

4a2d78b4d4 Give multiple-values objects a tc7 
* libguile/scm.h (scm_tc7_values): New tc7.  Never seen by Scheme, so we
  don't need to update it anywhere else.

  functions.
  (SCM_VALUESP): Use scm_is_value.

  representation.

  (scm_values, scm_c_values): Make the new-style objects, which store
  their values inline.
  (scm_values_2, scm_values_3): New helpers, to avoid consing little
  useless lists.

791eb0c01a Remove (C) from copyright statements 
As the FSF advises, 'There is no legal significance to using the
three-character sequence “(C)”, but it does no harm.'  It does take up
space though!  For that reason, we remove it here from our C files.

1d257c27f0 Do not assume that sizeof (long) == sizeof (void *) == sizeof (SCM). 
This assumption does not hold on systems that use the LLP64 data model.

Partially fixes <https://debbugs.gnu.org/22406>.
Reported by Peter TB Brett <peter@peter-b.co.uk>.

* libguile/numbers.h (scm_t_inum): Move here from numbers.c, and change
  to be equivalent to 'long' (formerly 'scm_t_signed_bits').
  (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Define based on
  SCM_I_FIXNUM_BIT instead of SCM_T_SIGNED_BITS_MAX.
  (SCM_I_INUM): Adjust definitions to return a 'scm_t_inum', and avoiding
  the assumption that SCM_UNPACK returns a 'long'.
* libguile/numbers.c (scm_t_inum): Move definition to numbers.h.
  Verify that 'scm_t_inum' fits within a SCM value.
  (scm_i_inum2big): Remove preprocessor code that forced a compile error
  unless sizeof (long) == sizeof (void *).
