[PATCH] D105806: [LV] Print remark when loop cannot be vectorized due to invalid costs.

- Added debug-info to test, and updated comment for `expectedCost`
- Changed the patch to emit individual remarks, with their corresponding debug-info, instead of a single remark where this info is all compiled together.

e.g.

t.c:4:19: remark: Instruction with invalid costs prevented vectorization at VF=(vscale x 1): load

  dst[i] = sinf(src[i]);
                ^

t.c:4:14: remark: Instruction with invalid costs prevented vectorization at VF=(vscale x 1, vscale x 2, vscale x 4): call to llvm.sin.f32

  dst[i] = sinf(src[i]);
           ^

t.c:4:12: remark: Instruction with invalid costs prevented vectorization at VF=(vscale x 1): store

  dst[i] = sinf(src[i]);
         ^
