[Lapack] does LOPT need update in dsyevd.f


hi.

i found a subtle difference between dsyevd.f and ssyevd.f when using lapack
3.4.1.

dsyevd updates LOPT after calling dsytrd and dlacpy. but those codes are
not visible in ssyevd.f, cheevd.f and zheevd.f.

pls refer to line 329, 344 in dsyevd.f.

i wonder whether those codes are necessary, because dsyevd has
precalculated LOPT with at least 1+6*N+2*N**2.

if those codes must be there, why not for ssyevd?

thanks in advance.
