  -----------
  [CodeGen][AMDGPU] Remove premature empty subrange elimination (#201263)

This commit removes a call to `removeEmptySubRanges` inside
`SplitEditor::rewriteAssigned` which removes empty subranges that may be
expected at a later stage. The empty subranges are eliminated by a later
call to `removeEmptySubRanges`.

Fixes https://github.com/llvm/llvm-project/issues/199337.
