  Log Message:
  -----------
  [InstCombine] Remove transformation on call instruction where return value need void to non-void conversion (#98536)

Skip simplification on call instruction where a non-void return value is
expected but the callee returns void, which is undefined behavior and
could lead to non-determinism or crashes.
