Based on patch from Daniel Berlin <dberlin@dberlin.org>.
	* buildsym.c: Include "demangle.h" for SYMBOL_INIT_DEMANGLED_NAME.
	(finish_block) For non-function blocks, hash the symbol table.  For
	function blocks, mark the symbol table as unhashed.
	* minsyms.c (msymbol_hash): Return hash value without taking modulus.
	(msymbol_hash_iw): Likewise.
	(add_minsym_to_hash_table): Take modulus of msymbol_hash's return
	value.
	(add_minsym_to_demangled_hash_table): Likewise for msymbol_hash_iw.
	(lookup_minimal_symbol): Likewise for both.
	* symtab.h (struct block): Add `hashtable' flag.  Comment the
	hashtable.
	(BLOCK_HASHTABLE, BLOCK_BUCKETS, BLOCK_BUCKET): New macro.
	(ALL_BLOCK_SYMBOLS): Update.
	(BLOCK_SHOULD_SORT): Do not sort hashed blocks.
	(struct symbol): Add `hash_next' pointer.
	* symtab.c (lookup_block_symbol): Search using the hash table when
	possible.
	(find_pc_sect_symtab): Use ALL_BLOCK_SYMBOLS.
	(search_symbols, find_addr_symbol): Likewise.

	* dstread.c (process_dst_block): Clear hashtable bit for new block.
	(read_dst_symtab): Likewise.
	* jv-lang.c (get_java_class_symtab): Likewise.
	* mdebugread.c: Include "gdb_assert.h".
	(shrink_block): Assert that the block being modified is not hashed.
	* coffread.c (patch_opaque_types): Use ALL_BLOCK_SYMBOLS.
	* symmisc.c (free_symtab_block): Walk the hash table when freeing
	symbols.
	(dump_symtab): Recognize hashed blocks.
	* printcmd.c (print_frame_args):  Assert that function blocks do not
	have hashed symbol tables.
	* ada-lang.c (symtab_for_sym): Use ALL_BLOCK_SYMBOLS.
	(fill_in_ada_prototype, debug_print_block): Likewise.
	(ada_add_block_symbols): Use ALL_BLOCK_SYMBOLS.  Handle hash tables.
