CL 123362 introduced a bug in creating alias type's backend
representation. A type's btype_ should not be set before
named types are converted if it is a placeholder. For alias
type, it is set too early. This may result in unresolved
placeholders. This CL fixes it.

Previously, when creating the backend representation of a
circular type, we resolve the placeholder to a
circular_pointer_type. The backend doesn't know what the
concrete type is.
This CL changes it to resolve the placeholder to the concrete
type instead, so the backend may have better knowledge of the
concrete type.

Use -Wabi=2 to fix warnings about -Wabi having no effect on its own.
This requires suppressing two warnings in src/c++11/debug.cc which do
not affect the library ABI.
Previously libstdc++ defaulted to --enable-werror but the -Werror flag
was not actually added unless --enable-maintainer-mode was used. This is
not documented and not the expected behaviour. This removes any special
treatment for maintainer-mode, makes -Werror depend directly on
--enable-werror, and changes the default to --enable-werror=no.

The explicit instantiation of std::call_once used to require an
instantiation of __bind_simple, but call_once was changed by r241031 to
not use __bind_simple. The instantiation of __bind_simple (and the
definitions it uses) are not needed. They should have been removed
instead of doing the changes in r241111 that kept them compiling.
The use of std::call_once by _Async_state_common::_M_join can be
simplified to use a pointer instead of reference wrapper. The call_once
symbol isn't exported so the change isn't visible outside the library.

This patch fixes a spurious error on a prefixed call in an instance, when the
generic parameters include an interface type and an abstract operation of that
type, and the actuals in the instance include an interface type and a
corresponding abstract operation of it, with a different name than the
corresponding generic subprogram parameter. The patch also fixes a similar
error involving class-wide operations and generic private types.
