	* dwarf2read.c (peek_abbrev_code): New function.
	(dw2_get_file_names): Check for dummy compilation units.
	(create_debug_types_hash_table): Likewise.
	(process_psymtab_comp_unit): Likewise.
	(load_partial_comp_unit): Likewise.
	(load_full_comp_unit): Likewise.

I did not debug it yet but it is a regression for many testcases iff
.debug_types are used.  Such as:

FAIL: gdb.base/call-ar-st.exp: print print_small_structs (pattern 6)
FAIL: gdb.base/call-ar-st.exp: step into print_long_arg_list
FAIL: gdb.base/call-ar-st.exp: print print_small_structs from print_long_arg_list (pattern 6)
FAIL: gdb.base/call-ar-st.exp: print print_bit_flags_combo from init_bit_flags_combo
