For the --enable-clocale=generic configuration, the current code can
fail with a bad_alloc exception. This patch uses the nothrow version of
operator new and reports allocation failures by setting failbit in the
iostate variable.

This adds the manipulators for use with basic_osyncstream. In order to
detect when an arbitrary basic_ostream is the base class of a
basic_syncbuf object, introduce a new intermediate base class
that stores the data members. The new base class stores a pointer and
two bools, which wastes (sizeof(vo

This patch introduces maybe_emit_call_builtin___clear_cache for the
builtin expander machinery and the trampoline initializers to use to
clear the instruction cache, removing a source of inconsistencies and
subtle errors in low-level machinery.
I've adjusted all trampoline_init implementations t
