Add support for storing local symbols in a small structure to save
memory when assembling large files. * as.h: Don't include struc-symbol.h. (symbolS): Add typedef. * symbols.c: Include struc-symbol.h. (local_hash): New static variable.

(symbol_begin): Initialize local_hash. (print_symbol_value_1): Handle local symbols. (symbol_print_statistics): Print local symbol statistics. * symbols.h: Include "struc-symbol.h" if not BFD_ASSEMBLER. Declare new symbols.c functions. Move many declarations here from struc-symbol.h. (SYMBOLS_NEED_BACKPOINTERS): Define if needed. * struc-symbol.h (SYMBOLS_NEED_BACKPOINTERS): Don't set. (struct symbol): Move bsym to make it clearly the first field. Remove TARGET_SYMBOL_FIELDS.
