* options.h (DEFINE_set): Add VARNAME_begin and VARNAME_end
functions.
(class General_options): Remove existing --undefined, and add
--no-undefined instead. Add new --undefined as synonym for -u.
* archive.cc (Archive::add_symbols): Check whether symbol was
named with -u.
* gold.cc (queue_middle_tasks): Add -u symbols to symbol table.
* symtab.h (class Symbol): Rename CONSTANT to IS_CONSTANT; change
all uses. Add IS_UNDEFINED. Update declarations to split
different versions of init_base. Declare init_base_undefined.
(Symbol::is_defined): Handle IS_UNDEFINED.
(Symbol::is_undefined): Likewise.
(Symbol::is_weak_undefined): Call is_undefined.
(Symbol::is_absolute): Handle IS_CONSTANT.
(class Sized_symbol): Update declarations to split different
versions of init. Declare init_undefined.
