In-place circshift!(arr, shifts)

[jariji]

The 3-arg form circshift!(dest, src, shifts) has the aliasing warning, but I commonly want to rotate in place. Can Base have in-place circshift!(arr, shifts)?

Turns out this method is already implemented, just not documented. Any reason not to document it?

julia/base/abstractarray.jl

Lines 3671 to 3681 in 58399e2

	function circshift!(a::AbstractVector, shift::Integer)
	n = length(a)
	n == 0 && return a
	shift = mod(shift, n)
	shift == 0 && return a
	l = lastindex(a)
	reverse!(a, firstindex(a), l-shift)
	reverse!(a, l-shift+1, lastindex(a))
	reverse!(a)
	return a
	end

I think this issue is a duplicate of #46016 after all.
