allow iflags to be constant expressions with typing-strictness==2
* libguile/tags.h (SCM_MAKE_ITAG8_BITS): New helper, produces a scm_t_bits instead of a SCM, because SCM_UNPACK is not a constant expression with SCM_DEBUG_TYPING_STRICTNESS==2. (SCM_MAKIFLAG_BITS): Remove SCM_MAKIFLAG, and replace with this, which returns bits. (SCM_BOOL_F_BITS, SCM_ELISP_NIL_BITS, SCM_EOL_BITS, SCM_BOOL_T_BITS): (SCM_UNSPECIFIED_BITS, SCM_UNDEFINED_BITS, SCM_EOF_VAL_BITS): (SCM_UNBOUND_BITS): New definitions. Defined SCM_BOOL_F, etc in terms of them. (SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_0): (SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_1): (SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_2): (SCM_XXX_ANOTHER_LISP_FALSE_DONT_USE): Be bits instead of SCM values. (SCM_BITS_DIFFER_IN_EXACTLY_ONE_BIT_POSITION): (SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS): Rename from SCM_VALUES_DIFFER_..., and take unpacked bits as the args. * libguile/boolean.c: Update verify block to use SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS et al. * libguile/debug.c (scm_debug_opts): * libguile/print.c (scm_print_opts): * libguile/read.c (scm_read_opts): Use iflags bits for initializers. * libguile/hash.c (scm_hasher): Use _BITS for iflags as case labels. * libguile/pairs.c: Nil/null compile-time check uses SCM_ELISP_NIL_BITS.
