[PATCH] testsuite/vect: Make check more accurate.

[Robin Dapp <rdapp.gcc@gmail.com>]

Hi,

similar to before this modifies a check so we do only match a
vectorization attempt if it succeeded.  On riscv we potentially try
several modes of which some may fail.

I tested on riscv, aarch64 and x86 but on the cfarm machines
there is no vect_fold_extract_last.  Maybe gcn would work?

Regards
 Robin
