  [MachineOutliner] Avoid ranges that cross bundle boundary (#148977)

We found some code that was hitting this assert because
`getOutlinableRanges()` was trying to create a range that crossed a
bundle boundary.


https://github.com/llvm/llvm-project/blob/ae3bba4d15a10646ea91c6c0795633b82939857b/llvm/include/llvm/CodeGen/MachineInstrBundleIterator.h#L133-L135

Avoid creating those ranges and add a test that hit the assert.
