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.

(cherry picked from commit fa37ac2b59ed1c379b35dbf9bd58f7849f9fd5b5)
