libstdc++: Fix call signature of builtins from masked ++/--
This resolves failures in the "expensive" where-* test of check-simd
when targeting AVX-512.
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
* include/experimental/bits/simd_x86.h (_S_masked_unary): Call
the 4- and 8-byte variants of __builtin_ia32_subp[ds] without
rounding direction argument.
(cherry picked from commit 0ac2c0f0687b321ab54de271d788b4e0a287b4e2)
