Recognize missing DW_AT_location as <value optimized out>.
* dwarf2read.c
(new_symbol <DW_TAG_variable> <!DW_AT_location> <!DW_AT_external>):
Call add_symbol_to_list.
gdb/testsuite/
* gdb.dwarf2/dw2-noloc-main.c: New file.
* gdb.dwarf2/dw2-noloc.S: New symbols matrix.
(.text): Remove.
(.data): New.
(DW_AT_stmt_list, .debug_line, DW_AT_frame_base): Remove.
(DW_AT_low_pc, DW_AT_high_pc): Reference `dw2-noloc-main.c'.
(DW_TAG_subprogram func_cu1, noloc): Remove.
(main): New.
* gdb.dwarf2/dw2-noloc.exp: Use prepare_for_testing, compile also
