* configure.ac (CC_HAS_LONG_LONG): Replace by AC_MSG_ERROR.
	* defs.h (LONGEST, ULONGEST): Remove conditionalization for
	CC_HAS_LONG_LONG.
	* dwarf2-frame.c (DW64_CIE_ID): Likewise.
	* dwarf2read.c (extract_cu_value): Remove the function.
	(create_cus_from_index_list): Make the return type void, inline the
	extract_cu_value caller, include new gdb_static_assert.
	(create_cus_from_index): Make the return type void, update the function
	comment, update the create_cus_from_index_list caller.
	(create_signatured_type_table_from_index): Make the return type void,
	inline the extract_cu_value caller, include new gdb_static_assert.
	(dwarf2_read_index): Update the create_cus_from_index and
	create_signatured_type_table_from_index caller.
