Add support for reshaped + reinterpreted arrays

julia> using SIMD

julia> a=rand(25,25);

julia> b=reinterpret(UInt8,a);

julia> c=vec(b);

julia> vload(Vec{32,UInt8}, c, 1)
ERROR: MethodError: no method matching vload(::Type{Vec{32, UInt8}}, ::Base.ReshapedArray{UInt8, 1, Base.ReinterpretArray{UInt8, 2, Float64, Matrix{Float64}, false}, Tuple{}}, ::Int64)

Closest candidates are:
