libstdc++-v3/ChangeLog:
* include/Makefile.am: Add simd_sve.h.
* include/Makefile.in: Add simd_sve.h.
* include/experimental/bits/simd.h: Add new SveAbi.
* include/experimental/bits/simd_builtin.h: Use
__no_sve_deduce_t to support existing Neon Abi.
* include/experimental/bits/simd_converter.h: Convert
sequentially when sve is available.
* include/experimental/bits/simd_detail.h: Define sve
specific macro.
* include/experimental/bits/simd_math.h: Fallback frexp
to execute sequntially when sve is available, to handle
fixed_size_simd return type that always uses sve.
* include/experimental/simd: Include bits/simd_sve.h.
* testsuite/experimental/simd/tests/bits/main.h: Enable
testing for sve128, sve256, sve512.
