Switch execution to native assembly generation

Some examples showing different cases of path for nodes that allows merging exec paths, such as branch.
Note the last one shows a case that is technically not possible without "Goto", which has to be caught automatically by the system:

[snakex64]

When merging back isn't allowed, such as "ForEach", it is much easier as any path that are hit by any multiple combination of execs will automatically be disallowed :

[snakex64]

Some path allow external execution to merge in, such as the "After Loop" of a "ForEach". It would represent something like :

if(...) {
    foreach(...) {
        some code
    }
    some code
}
some code

Dead ends also need to be taken into account. Some path do not allow having dead ends, such as "Branch". You cannot just "Stop" the execution inside a "If". You can, on the other hand, "Stop" execution inside a loop, which means simply continuing the next iteration. The following graph also shows are "Allowing" dead end takes priority over "Not allowing it"

Another complex merging option is when 2 path are merging back together at the exact same time as another path so happens to go there, it can lead to complex multi-path-merges. Both these examples are technically valid, though it might be easier to implement by forcing the user to add a useless node to remerge one branch at a time ?
