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.
