    cmd/compile: remove funcdepth variables · d7eb4901
    Matthew Dempsky authored
    There were only two large classes of use for these variables:
    
    1) Testing "funcdepth != 0" or "funcdepth > 0", which is equivalent to
    checking "Curfn != nil".
    
    2) In oldname, detecting whether a closure variable has been created
    for the current function, which can be handled by instead testing
    "n.Name.Curfn != Curfn".
    
    Lastly, merge funcstart into funchdr, since it's only called once, and
    it better matches up with funcbody now.
    
    Passes toolstash-check.
