svdvals! has no method for Array{BigFloat,2}, causing norm2(::Array{BigFloat,2}) to error

[ChrisRackauckas]

The function svdvals! does not have a method for Array{BigFloat,2}. This is an issue because, as in the attached clip, it's pretty common to use the 2-norm of matrices, which inevitably calls svdvals! and fails.

Simple example:

A = map(BigFloat,rand(4,2))
norm(A,2)

You can use GenericSVD.jl: we should try to move this into Base at some point.

Closing because this works. Instead of moving to Base, this should probably move to LinearAlgebra.jl, which should move to JuliaMath.
