Integrate:

[ 32483]
Use a new (clean) anonymous hash for each loop, rather than a hash in
the pad, as the latter can change internal state sufficiently to
confuse matters (even though in all cases it has no keys and from
Perl space is "measurably" identical).

[ 32500]
Get APItest.xs compiling on 5.8.x by making the compilation of the
Perl_hv_common() test code conditional on the macro hv_common being
defined, and the refcounted_he code conditional on it being 5.9 or
later.

[ 32501]
Hack round the fact that UNITCHECK is nothing special on 5.8.x by
conditionally creating a sub UNITCHECK(&);

[ 32502]
UNITCHECK isn't anything special in 5.8.x, so don't run those tests.

[ 32503]
Skip the op.t API test as it's not relevant to 5.8.x (%^H propagation).
Correct the expectations of hash.t and svsetsv.t for 5.8.x.

[ 32507]
Test both dMY_CXT and dMY_CXT_INTERP.
