c, middle-end: Implement C2Y N3747 paper - Integer Sets, v5

C23 disallowed signed _BitInt(1), it only allowed unsigned _BitInt(1)
and signed _BitInt(2) and larger precisions.
The https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3747.pdf paper
changes this for C2Y and allows signed _BitInt(1) and (backwards
incompatibly) changes the type of 0wb from _BitInt(2) to _BitInt(1),
all other literals keep their earlier types.  The paper contains large
redesign of the C types hierarchy, but my understanding is that only
those two changes are changing something for users.

2026-04-28  Jakub Jelinek  <jakub@redhat.com>

gcc/
	* tree.cc (build_bitint_type): Allow build_bitint_type (1, 0).
	(signed_or_unsigned_type_for): Call that for !unsignedp case
	of BITINT_TYPE with bits 1.
gcc/c-family/
	* c-common.cc (c_common_signed_or_unsigned_type): Use
	build_bitint_type for TREE_CODE (type) == BITINT_TYPE whenever
	flag_isoc2y even when precision is 1.
	(c_common_get_alias_set): Don't special case BITINT_TYPE
	with precision 1 for flag_isoc2y.
	* c-lex.cc (interpret_integer): Use _BitInt(1) type for 0wb
	if flag_isoc2y, rather than _BitInt(2).
gcc/c/
	* c-decl.cc (finish_declspecs) <case cts_bitint>: Implement
	C2Y N3747 - Integer Sets, v5.  Allow signed _BitInt(1) for
	flag_isoc2y.
gcc/testsuite/
	* gcc.dg/torture/bitint-96.c: New test.
	* gcc.dg/torture/bitint-97.c: New test.
	* gcc.dg/torture/bitint-98.c: New test.
	* gcc.dg/bitint-130.c: New test.
	* gcc.dg/bitint-131.c: New test.
	* gcc.dg/bitint-132.c: New test.
