libstdc++: Add missing constexpr on simd shift implementation
Resolves -Wtautological-compare warnings about `if
(__builtin_is_constant_evaluated())` in the implementations of these
functions.
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
* include/experimental/bits/simd_x86.h (_S_bit_shift_left)
(_S_bit_shift_right): Declare constexpr. The implementation was
already expecting constexpr evaluation.
