[committed][testsuite] Require non_strict_align in pr94600-{1,3}.c

[Tom de Vries]

Hi,

With the nvptx target, we run into:
...
FAIL: gcc.dg/pr94600-1.c scan-rtl-dump-times final "\\(mem/v" 6
FAIL: gcc.dg/pr94600-1.c scan-rtl-dump-times final "\\(set \\(mem/v" 6
FAIL: gcc.dg/pr94600-3.c scan-rtl-dump-times final "\\(mem/v" 1
FAIL: gcc.dg/pr94600-3.c scan-rtl-dump-times final "\\(set \\(mem/v" 1
...
The scans attempt to check for volatile stores, but on nvptx we have memcpy
instead.

This is due to nvptx being a STRICT_ALIGNMENT target, which has the effect
that the TYPE_MODE for the store target is set to BKLmode in
compute_record_mode.

Fix the FAILs by requiring effective target non_strict_align.

Tested on nvptx.

Committed to trunk.

Thanks,
- Tom
