maximum of Any array

[bjarthur]

if maximum(tmp) succeeds when tmp::Array{Any}, shouldn't maximum(tmp,1) succeed as well?

julia> tmp = convert(Array{Any},rand(3,4))
3x4 Array{Any,2}:
 0.781922  0.765787  0.714231   0.787834
 0.715081  0.118564  0.0907171  0.624957
 0.884211  0.285455  0.217336   0.777541

julia> maximum(tmp)
0.8842111707356262

julia> maximum(tmp,1)
ERROR: `zero` has no method matching zero(::Type{Any})

same fundamental question/decision as #8319?

closing as a dup of 8319.
