; When masked-interleaved-groups are disabled:
; Check that the predicated load is not vectorized as an
; interleaved-group but rather as a scalarized accesses.
; (For SKX, Gather is not supported by the compiler for chars, therefore
;  the only remaining alternative is to scalarize).
; In this case a scalar epilogue is not needed.
;
; When  masked-interleave-group is enabled we expect to find the proper mask
; shuffling code, feeding the wide masked load for an interleave-group (with
; a single member).
; Since the last (second) member of the load-group is a gap, peeling is used,
; so we also expect to find a scalar epilogue loop.

; When masked-interleave-group is disabled the interleave-groups will be
; invalidated during Legality checks; So there we check for no epilogue
; and for scalarized conditional accesses.
; When masked-interleave-group is enabled we check that there is no epilogue,
; and that the interleave-groups are vectorized using proper masking (with
; shuffling of the mask feeding the wide masked load/store).
; The mask itself is an And of two masks: one that masks away the remainder
; iterations, and one that masks away the 'else' of the 'if' statement.
; The shuffled mask is also And-ed with the gaps mask.

; Same, with stride 3. This is to check the gaps-mask and the shuffled mask
; with a different stride.
; So accesses are with gaps under Optsize scenario again, with unknown trip-
; count, in order to check the behavior of folding-the-tail (folding the
; remainder loop into the main loop using masking) together with interleaved-
; groups.
; When masked-interleave-group is enabled we check that there is no epilogue,
; and that the interleave-groups are vectorized using proper masking (with
; shuffling of the mask feeding the wide masked load/store).
; The mask itself is an And of two masks: one that masks away the remainder
; iterations, and one that masks away the 'else' of the 'if' statement.
; The shuffled mask is also And-ed with the gaps mask.

; Back to stride 2 with gaps with a known trip count under opt for size,
; but this time the load/store are not predicated.
; When enable-masked-interleaved-access is disabled, the interleave-groups will
; be invalidated during cost-model checks because we have gaps and we can't
; create an epilog. The access is thus scalarized.
; (Before the fix that this test checks, we used to create an epilogue despite
; optsize, and vectorized the access as an interleaved-group. This is now fixed,
; and we make sure that a scalar epilogue does not exist).
; When enable-masked-interleaved-access is enabled, the interleave-groups will
; be vectorized with masked wide-loads (masking away the gaps).

; Unconditioal accesses with gaps under Optsize scenario again, with unknown
; trip-count this time, in order to check the behavior of folding-the-tail
; (folding the remainder loop into the main loop using masking) together with
; interleaved-groups. Folding-the-tail turns the accesses to conditional which
; requires proper masking. In addition we need to mask out the gaps (all
; because we are not allowed to use an epilog due to optsize).
; When enable-masked-interleaved-access is disabled, the interleave-groups will
; be invalidated during cost-model checks. So there we check for no epilogue
; and for scalarized conditional accesses.
; When masked-interleave-group is enabled we check that there is no epilogue,
; and that the interleave-groups are vectorized using proper masking (with
; shuffling of the mask feeding the wide masked load/store).
; The shuffled mask is also And-ed with the gaps mask.

; Full groups under Optsize scenario again, with unknown trip-count, again in
; order to check the behavior of folding-the-tail (folding the remainder loop
; into the main loop using masking) together with interleaved-groups.
; This time the accesses are not conditional, they become conditional only
; due to tail folding.
; When masked-interleave-group is disabled the interleave-groups will be
; invalidated during cost-model checks, so we check for no epilogue and
; scalarized conditional accesses.
; When masked-interleave-group is enabled we check for no epilogue,
; and interleave-groups vectorized using proper masking (with
; shuffling of the mask feeding the wide masked load/store).
; (Same vectorization scheme as for the previous loop with conditional accesses
; except here the mask only masks away the remainder iterations.)
