SVE support for WoA

[zafeerali943]

Does LLVM clang-cl compiler can compile SVE intrinsic on Windows on ARM machine?
If yes, how could I compile SVE codes on WoA?

Sample code:

#include <arm_sve.h>

int accumulate(svint64_t a, svint64_t b) {
svbool_t p = svptrue_b64();
return svaddv(p, svmla_z(p, a, a, b));
}

int main(void)
{
svbool_t p = svptrue_b64();
svint64_t a = svdup_s64(1);
svint64_t b = svdup_s64(2);
return accumulate(a, b);
}

Which means SVE code could not be compiled on WoA with latest clang-cl?

Yes, but I think you can use SVE ASM
