build: go faster, drop -fno-omit-frame-pointer #44452

  1. build: go faster, drop -fno-omit-frame-pointer

    This flag was added back in 2013 to support postmortem debugging on
    Linux but it has a pretty bad impact on performance (up to 10%) and
    I don't think it's actually necessary to get meaningful stack traces.
    Maybe with mdb but gdb and lldb seem to manage just fine.
    
    Even if the flag is necessary for postmortem debugging, I don't think
    it's appropriate to make performance for all users suffer for the
    benefit of a fringe group.
