typeintersect: convert union of tuples to tuple of unions (#27573) * Resolve an ambiguity for `\` Resolve the ambiguity between `(\)(::Union{QR,QRCompactWY,QRPivoted},::AbstractVecOrMat)` and `(\)(::Factorization, ::Diagonal)` by defining `(\)(::Union{QR,QRCompactWY,QRPivoted}, ::Diagonal)` to `invoke` the former. * Resolve an ambiguity for `BroadcastStyle` Resolve the ambiguity between `BroadcastStyle(::SPVM, ::AbstractArrayStyle{0})` and `BroadcastStyle(::AbstractArrayStyle{M}, ::DefaultArrayStyle{N})` by defining `BroadcastStyle(::SPVM, ::DefaultArrayStyle{0})` equivalent to the former. * Resolve an ambiguity for `\` Resolve the ambiguity between `(\)(::Factorization{T}, ::VecOrMat{Complex{T}}) where T<:BlasReal` and `(\)(::QRSparse, ::StridedVecOrMat)` by widening `(\)(::QRSparse{Float64}, ::VecOrMat{Complex{Float64}})` to `(\)(::QRSparse{T}, ::VecOrMat{Complex{T}}) where T<:BlasReal`. * Only prevent typeintersect from returning a Union if both arguments are Tuples * Convert a union of tuples to a tuple of unions in typeintersect This may potentially widen the result, but is better than just returning the second argument instead.
