givens does not work with integer vectors

[hurak]

The function givens (Julia v1.1.1) does not work properly with vectors with integer arguments. An example code is below:

using LinearAlgebra
x = [3,4]
G,r = givens(x,1,2)

it returns

ERROR: MethodError: no method matching givensAlgorithm(::Int64, ::Int64)
Stacktrace:
 [1] givens(::Int64, ::Int64, ::Int64, ::Int64) at /buildworker/worker/package_linux64/build/usr/share/julia/stdlib/v1.1/LinearAlgebra/src/givens.jl:276

 [3] top-level scope at none:0

If instead the vector x contains floats, there are no problems:

x = [3.0,4.0]
G,r = givens(x,1,2)

yielding

(LinearAlgebra.Givens{Float64}(1, 2, 0.6, 0.8), 5.0)
