their unchecked equivalents in that they take the shift amount as a uint,
instead of an int.

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.

Most of the expected output files of these test cases were
easily readable already, but there were some exceptions caused
by unnecessary differences between their source codes.
The main problem was with bitwise_uint.m (uint_bitwise.m until recently),
whose .exp file contained very long lines of the form A op B = C
where A, B and C could each be 64 bits (and chars) long. Fix this
by adopting the format used by the other modules:
A op
B =
C
The other problem was that in some test cases, the indentation had
an off-by-one bug. They generated output such as
\ aaaa =
bbbb
instead of the much-easier-to-visually-check
\ aaaa =
bbbb
A third, much less important change is the deletion of unnecessary
blank lines.
