Instability with obfuscation

Ollvm14 is not fully stable, some flags cause compiler to hang or crash unexpectedly, unlike https://github.com/o2e/OLLVM-9.0.1 which is fully stable and can use many flags combination

-sub_loop=3 and above cause compiler to hang

-sub_loop=5 and above causing huge memory leak

-bcf_loop=3 and above cause compiler to hang and reports LLVM ERROR: out of memory

aesSeed= may cause ld: error: duplicate symbol:

And a few combination caused crash
