LoopVectorization fail to compile on julia 32bit REPL

[kaihsin]

Platform:
> linux x86_64 with julia 32bit REPL (v1.6.7 lts)

Issue:
> LoopVectorization fail to compile due to missing method
> mulexpr(::SubArray{Any, 1, Vector{Any}, Tuple{UnitRange{Int32}}, true})

How to reproduce:
> on x86_64 (64bit linux OS) using julia 32bit REPL to install LoopVectorization

Cause:
> I believe it is because the default Base.Int is Int32 on 32bit REPL, in oppose to 64bit REPL where Base.Int is Int64, therefore the Tuple{UnitRange{Int32}} is not implemented
