Mult dim reverse

for #29871

I noticed something while working on this, which I think is related to #9498
There exists a method reverse(::Array; dims=::Integer).
I created a method reverse(::AbstractArray; dims)

If I call reverse(somearray, dims=sometuple) it presently seems to attempt to call reverse(::Array; dims=::Integer), for which types do not match, rather than reverse(::AbstractArray; dims) for which types do match.

My solution for now is to rename conflicting methods _reverse, so that they will be "private" and called by reverse(::AbstractArray; dims) when dims is scalar. These should probably be renamed back if #9498 is ever fixed.

As a side note, I noticed that there is code duplication between different reverse/_reverse methods. It's not a big deal I think, but it'd make sense to abstract the common components to something.

Hm, I don't see how those two build problems could relate to base. Can anyone point me where to start to make these checks pass?

I can't see how my changes could cause either of these errors for win32 build (rm: cannot remove 'share/julia/test': Device or resource busy)
(command timed out: 3600 seconds without output running ['bin/julia.exe', '-e', 'Base.runtests(["all"]; ncores=min(Sys.CPU_THREADS, 8))'], attempting to kill) or xcode test (Code:ERROR, Class:Net, curl error: Could not resolve host: github.com). I'd really like to merge this though, it's needed for an issue in DSP. Is it possible there was a temporary problem with the server that runs the CI? If that's possible, could someone run again?
