(scm_from_uint32): Reimplement inline.
* libguile/integers.c (make_bignum_2):
(make_bignum_from_uint64):
(negative_uint32_to_int32):
(positive_uint32_to_int32):
(bignum_to_int32):
(bignum_to_uint32):
(scm_integer_from_int32):
(scm_integer_from_uint32):
(scm_integer_to_int32_z):
(scm_integer_to_uint32_z): Better int32 support for 32-bit machines.
