[START:END:STEP].  The value is always at least 1.

starts with these explicitly-encoded elements and may contain additional
elided elements.

		bool	allow_stepped_p )

inherited

Try to start building a new vector of shape SHAPE that holds the result of
a binary operation on vector constants VEC1 and VEC2.  ALLOW_STEPPED_P is
true if the operation can handle stepped encodings directly, without
having to expand the full sequence.

otherwise.

inherited

Try to start building a new vector of shape SHAPE that holds the result of
a unary operation on vector constant VEC.  ALLOW_STEPPED_P is true if the
operation can handle stepped encodings directly, without having to expand
the full sequence.

Return true if the operation is possible, which it always is when
ALLOW_STEPPED_P is true.  Leave the builder unchanged otherwise.
