    cmd/compile: fix DWARF type symbol buglet · 9372166f
    Than McIntosh authored
    The code that generates the list of DWARF variables for a function
    (params and autos) will emit a "no-location" entry in the DWARF for a
    user var that appears in the original pre-optimization version of the
    function but is no longer around when optimization is complete. The
    intent is that if a GDB user types "print foo" (where foo has been
    optimized out), the response will be "<optimized out>" as opposed to
    "there is no such variable 'foo'). This change fixes said code to
    include vars on the autom list for the function, to insure that the
    type symbol for the variable makes it to the linker.
    
    Fixes #22941.
