As above. The unchecked versions have only declarations, since
these operations have been recognized as builtins for a while now.
NEWS:
Document the new operations, and the recent change to recognize
<<u and >>u as single tokens, and fix a typo in a recent addition.
configure.ac:
Require the compiler to be sufficiently recent to be able to parse
<<u and >>u as operators.
compiler/options.m:
Provide a way for a later change to configure.ac to detect the presence
of this change.
