Consistently use asm volatile ("" ::: "memory") in vect tests

The vectoriser tests used a combination of:

1) if (impossible condition) abort ();
2) volatile int x; ... *x = ...;
3) asm volatile ("" ::: "memory");

to prevent vectorisation of a set-up loop.  The problem with 1) is that
the compiler can often tell that the condition is false and optimise
it away before vectorisation.

This was already happening in slp-perm-9.c, which is why the test was
expecting one loop to be vectorised even when the required permutes
weren't supported.  It becomes a bigger problem with SVE, which is
able to vectorise more set-up loops.

The point of this patch is therefore to replace 1) with something else.
2) should work most of the time, but we don't usually treat non-volatile
accesses as aliasing unrelated volatile accesses, so I think in principle
we could split the loop into one that does the set-up and one that does
the volatile accesses.  3) seems more robust because it's also a wild
read and write.

The patch therefore tries to replace all instances of 1) and 2) with 3).
