Question: clarify the usage of -fno-omit-frame-pointer

For amd64, `-fno-omit-frame-pointer` is set.
https://github.com/intel/hyperscan/blame/master/CMakeLists.txt#L271

We have occasionally removed this flag from build and have hit the bug immediately:
https://github.com/ClickHouse/ClickHouse/pull/11718
because asynchronous stack unwinding from `roseRunProgram` function started to lead to segfault.

I did not find any information about the reason why the flag `-fno-omit-frame-pointer` is required (there is no comments in your CMakeLists.txt file).

My hypothesis is the following:
> It looks like that computed gotos in Hyperscan jumps into the code of different functions and back. And without saving frame pointer, unwinding cannot work.

Am I right?
