libstdc++: Simplify calculation of expected value in simd test
This avoids a failure on PR109964.
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
* testsuite/experimental/simd/tests/integer_operators.cc:
Compute expected value differently to avoid getting turned into
a vector shift.
