Remove explicit dg-do runs from gcc.dg/vect (PR 83889)

The failures in this PR were from forcing { dg-do run } even when
vect.exp chooses options that are incompatible with the runtime.
The default vect.exp behaviour is to execute when possible, so there's
no need for a dg-do at all.

The patch removes other unconditional { dg-do run }s too.  Many of them
were already failing in the same way.

Also, the dg-do run condition in vect-reduc-or* seems unnecessary:
the test should run correctly whatever happens, and the scan tests
are already guarded properly.
