[Bug fortran/24520] Temporary constant array descriptors being declared at wrong binding level.

binding level.

Andrew,

It turns out that the real overhead is the function call.  I posted a patch to
inline DOT_PRODUCT, which performs better than the library version.  It is on
my list of things to do that I resubmit this patch - it needs a changeover from
inline to library at a vector length ~16-32.  I need to study this as a
function of platform and arrya reference types.

Best regards

Paul
