searchsorted* with kwargs produces overwritten warning; at-which can't find def

[kmsquire]

While building (e.g., from https://travis-ci.org/JuliaLang/julia/jobs/186247003#L873-L875):

WARNING: Method definition searchsortedfirst(AbstractArray{T<:Any, 1}, Any) in module Sort at sort.jl:198 overwritten at sort.jl:201.
WARNING: Method definition searchsortedlast(AbstractArray{T<:Any, 1}, Any) in module Sort at sort.jl:198 overwritten at sort.jl:201.
WARNING: Method definition searchsorted(AbstractArray{T<:Any, 1}, Any) in module Sort at sort.jl:198 overwritten at sort.jl:201.

@which cannot find the function either, (it should be the version at sort.jl:198), although the function call does work:

julia> searchsorted([3,2,1], 1.5, rev=true)
3:2

julia> @which searchsorted([3,2,1], 1.5, rev=true)
(::Base.Sort.#kw##searchsorted)(::Array{Any,1}, ::Base.Sort.#searchsorted, v::AbstractArray{T<:Any,1}, x) in Base.Sort

julia> @which searchsorted([1,2,3], 1.5)
searchsorted(v::AbstractArray{T<:Any,1}, x) in Base.Sort at sort.jl:201

Note that this issue existed before #17057 was merged, although I haven't bisected (and don't really have time to right now).

Ok, thanks. I remember seeing those now. The at-which error is just fallout, I guess.
