[BUG]: filtering for the gcc optimization dumps makes things hard to handle

Describe the bug

I am trying to debug why we get a specific IR from the source and the before inlining dumps remove all of the non-user functions from the listing. This is very useless. Please have an option to disable this.

Also don't enable lineno by default and then filter it off; that leaves behind other artifacts in the dump that makes it hard to understand still.

Steps to reproduce

Take:

#include <vector>
void ff(std::vector<int> &a)
{
  a.push_back(1);
}

Expected behavior

Seeing more than just ff in the forwprop1 dump (pre-inlining). That is seeing push_back and other libstdc++ functions.
