ctf: fix integer truncations in very large structs [PR121411]HEADtrunkmaster

DWARF to CTF translation for type bit sizes was using uint32_t, and for
member offsets was inadvertently using unsigned int via get_AT_unsigned.
For very large struct types, at least one of these could be truncated
causing incorrect encoding of the struct type and member offsets.

Use HOST_WIDE_INT to avoid these truncation issues and fix the encoding
for large structs.

	PR debug/121411

gcc/

	* dwarf2ctf.cc (ctf_get_AT_data_member_location) Use AT_unsigned
	when fetching AT_bit_offset and AT_data_member_location.  Simplify.
	(ctf_die_bitsize): Return unsigned HOST_WIDE_INT instead of
	uint32_t.
	(gen_ctf_base_type, gen_ctf_sou_type, gen_ctf_enumeration_type):
	Adapt accordingly.

gcc/testsuite/

	* gcc.dg/debug/ctf/ctf-struct-3.c: New test.
