  [SLP][AMDGPU] Fix test to actually exercise count-check condition (#222022)

The gfx906 RUN lines in `inst-count-heuristic.ll` never exercised the
`SLPInstCountCheck` heuristic they were meant to test.
This patch converts the test kernel from `i32` to `i16` elements so the
heuristic's `getVectorFactor() == 2` gate is actually reachable on
gfx906, and adds a `-slp-inst-count-check=false` RUN line to cover the
non-default behavior.
