Loading LoopVectorization.jl makes push! error on julia1.9.0-beta2

[Kolaru]

Somehow loading the package makes push! with multiple arguments fail with a BoundsError on the latest julia beta.

Initially reported in Kolaru/MathTeXEngine.jl#97

julia> push!(a, 2, 3, 4)

I cannot reproduce.

is truly bizarre -- why is it calling push! with 4 arguments???

[chriselrod]

Mind testing if you still see the problem using #461?

https://github.com/JuliaSIMD/LoopVectorization.jl#nogratuitousoverloads fixes it for me on OS: Linux (x86_64-linux-gnu)
CPU: 64 × AMD EPYC 7371 16-Core Processor.

That PR deleted a push!(::LoopSet, ...) method by naming it _push! instead, as there was no reason to use the same name.

Seems like a Julia bug that this should have somehow influenced push!(::Vector{Any}.
Still, no reason to use the name push! over anything else, so I'll issue a new release as soon as that PR merges.

Also JuliaLang/julia#48085

[Kolaru]

#461 Also fixes it for me.
