[PATCH] D91806: [SVE] Remove warnings from release notes example on SVE ACLE.

fpetrogalli added a comment.

I have removed the C test, as the LL test is enough to test the changes I have done in `Local.cpp`.

I can confirm that with this patch, the release note ton'r raise any warnings when compiling with debug info:

  frapet01 at man-08:~/projects/upstream-clang/build-clang$ cat ../release-notes.c
  #include <arm_sve.h>
  
  void VLA_add_arrays(double *x, double *y, double *out, unsigned N) {
    for (unsigned i = 0; i < N; i += svcntd()) {
      svbool_t Pg = svwhilelt_b64(i, N);
      svfloat64_t vx = svld1(Pg, &x[i]);
      svfloat64_t vy = svld1(Pg, &y[i]);
      svfloat64_t vout = svadd_x(Pg, vx, vy);
      svst1(Pg, &out[i], vout);
    }
  }
  frapet01 at man-08:~/projects/upstream-clang/build-clang$ ./bin/clang --target=aarch64-gnu-linux -march=armv8-a+sve -c -g -S -O3 -o /dev/null ../release-notes.c
  frapet01 at man-08:~/projects/upstream-clang/build-clang$                        

When the patch will end up into a nightly build of compiler explorer, the compilation at this link should not raise any warnings: https://godbolt.org/z/zebzKM
