I'm not entirely sure about the original intent. This retains the current
behaviour of the test. Disabling LSR is necessary for that, and doing things
like so doesn't harm coverage. I don't know that I want to go and fully
re-develop this particular test at this point (it probably should be redone,
I'm just not entirey keen since I'm not entirey sure what is desired), as part
of this particular change. Doing it as strictly IR-to-IR would bypass the
original intent of the SPIR-V folks here, which seems centered around lowering
the staturated ops.
