  -----------
  [LV] Add tests for incorrect narrowing of IGs with scalable vectors.

Add test coverage for mis-compile in https://github.com/llvm/llvm-project/issues/185860.

Currently a wide load gets incorrectly narrowed to a single-scalar one
with scalable VFs, which only loads one element instead of the needed
vscale elements.
