Like for many other targets that skip this test, the value of
MOVE_RATIO of the target can simply be too small for SRA to consider
total scalarization profitable.

With the current trunk you can easily verify this by compiling the
testcase with -fdump-tree-sra-details and then looking into the SRA
dumps.  If they contain the string "Too big to totally scalarize: "
then this is exactly the issue.  In such case, please skip the test on
the target.  If not, then let me known here.  Thanks.
