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.

(cherry picked from commit 3e2689e568425f14d6728504ad6f5d32b90320ad)
