  -----------
  [InstCombine] Adding testcase for Z / (1.0 / Y) => (Y * Z); NFC

The added testcase shows the current transformation for the operation
Z / (1.0 / Y), which remains unchanged. This will be updated to align
with the transformed code (Y * Z) with D72319.

The existing transformation Z / (X / Y) => (Y * Z) / X is not handling
this case as there are multiple uses for (1.0 / Y) in this testcase.
