ea8b4aff - Aggressive constprop in trevc! to stabilize triangular eigvec (#54635)

Aggressive constprop in trevc! to stabilize triangular eigvec (#54635) We may use aggressive constprop in `trevc!` to eliminate branches, which makes the return type of `eigvec(::UpperTriangular)` concretely inferred. ```julia julia> @inferred eigvecs(UpperTriangular([1 0; 0 1])) 2×2 Matrix{Float32}: 1.0 -0.0 0.0 1.0 ```
