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.
