Remove make_cleanup_htab_delete

This removes make_cleanup_htab_delete in favor of destructors,
building on an earlier patch that added the htab_up typedef.

Testing revealed that more cleanup-removal work was needed in
dwarf2loc.c, so this version of the patch changes code there to use
unordered_set and vector, removing some more cleanups.

2017-01-10  Tom Tromey  <tom@tromey.com>

	* utils.h (make_cleanup_htab_delete): Don't declare.
	* utils.c (do_htab_delete_cleanup, make_cleanup_htab_delete):
	Remove.
	* linespec.c (decode_compound_collector): Add constructor,
	destructor.
	(lookup_prefix_sym): Remove cleanup.
	(symtab_collector): Add constructor, destructor.
	(collect_symtabs_from_filename): Remove cleanup.
	* disasm.c (do_mixed_source_and_assembly): Use htab_up.
	* compile/compile-c-symbols.c (generate_c_for_variable_locations):
	Use htab_up.
	* gnu-v3-abi.c (gnuv3_print_vtable): Use htab_up.
	* dwarf2read.c (dw2_expand_symtabs_matching)
	(dw2_map_symbol_filenames, dwarf_decode_macros)
	(write_psymtabs_to_index): Use htab_up.
	* dwarf2loc.c (func_verify_no_selftailcall)
	(call_site_find_chain_1, func_verify_no_selftailcall)
	(chain_candidate, call_site_find_chain_1): Use std::unordered_set,
	std::vector, gdb::unique_xmalloc_ptr.
	(call_sitep): Remove typedef.
	(dwarf2_locexpr_baton_eval): Remove unused variable.
