Ehud Katz 85c3088049 [StructurizeCFG] Fix region nodes ordering
This is a reimplementation of the `orderNodes` function, as the old
implementation didn't take into account all cases.
The new implementation uses SCCs instead of Loops to take account of
irreducible loops.

Ehud Katz c6c265527d Revert "[StructurizeCFG] Fix region nodes ordering"
This reverts commit 897d8ee5cd,
due to causing an infinite loop when encountering a loop with
a sub-region with an inner loop.
