[PATCH] S/390: Improve result verification in test case vec-genmask-1.c.

[Dominik Vogt]

THe attached patch improves checking of teh results of the
subtests "a" and "f".  As they share the same "vone" instruction,
the duplicate scan-assembler-times was bogus.  Moved "f" to a
separate function to fix this.  Also double check that no extra
"vgmf" instructions are used.

Ciao
