Remove null_block_symbol
This removes null_block_symbol. It seemed simpler to me to change initializations and returns to use value initialization rather than null_block_symbol. This also fixes up a few spots where initialization was done piecemeal. gdb/ChangeLog 2019-03-24 Tom Tromey <tom@tromey.com> * ada-lang.c (standard_lookup): Simplify initialization. (ada_lookup_symbol_nonlocal): Simplify return. * solib-spu.c (spu_lookup_lib_symbol): Simplify return. * solib-darwin.c (darwin_lookup_lib_symbol): Simplify return. * solib-svr4.c (elf_lookup_lib_symbol): Simplify return. * rust-lang.c (rust_lookup_symbol_nonlocal): Simplify initialization. * solib.c (solib_global_lookup): Simplify. * symtab.c (null_block_symbol): Remove. (symbol_cache_lookup): Simplify returns. (lookup_language_this): Simplify returns. (lookup_symbol_aux): Simplify return. (lookup_local_symbol): Simplify returns. (lookup_global_symbol_from_objfile): Simplify return. (lookup_symbol_in_objfile_symtabs) (lookup_symbol_in_objfile_from_linkage_name): Simplify return. (lookup_symbol_via_quick_fns, lookup_symbol_in_static_block) (lookup_static_symbol, lookup_global_symbol): Simplify return. * cp-namespace.c (cp_lookup_bare_symbol) (cp_search_static_and_baseclasses, cp_lookup_symbol_via_imports) (cp_lookup_symbol_via_all_imports, cp_lookup_nested_symbol_1) (cp_lookup_nested_symbol): Don't use null_block_symbol. (cp_lookup_symbol_via_imports): Simplify initialization. (find_symbol_in_baseclass): Likewise. * symtab.h (null_block_symbol): Remove. * d-namespace.c (d_lookup_symbol): Don't use null_block_symbol. (d_lookup_nested_symbol, d_lookup_symbol_imports) (d_lookup_symbol_module): Likewise. (find_symbol_in_baseclass): Simplify initialization.
