* Fix for T3286 in new codegen (related to T3132); plus formatting
Ignore-this: c23b1aed37be610552a7dba6d32cd923
If the scrutinee is bottom, the generated Cmm code could have a
type error when the case arm expected an unboxed floating-point
value (even though the arm should never be reached).
Now, we detect this case and avoid producing the type-incorrect
assignment.
