[MachineOutliner] Leaf Descendants (#90275)
This PR depends on https://github.com/llvm/llvm-project/pull/90264
In the current implementation, only leaf children of each internal node
in the suffix tree are included as candidates for outlining. But all
leaf descendants are outlining candidates, which we include in the new
implementation. This is enabled on a flag `outliner-leaf-descendants`
which is default to be true.
The reason for _enabling this on a flag_ is because machine outliner is
not the only pass that uses suffix tree.
The reason for _having this default to be true_ is because including all
leaf descendants show consistent size win.
* For Clang/LLD, it shows around 3% reduction in text segment size when
compared to the baseline `-Oz` linker binary.
* For selected benchmark tests in LLVM test suite
