    cmd/compile: mark temps with new AutoTemp flag, and use it. · 9c066bab
    David Chase authored
    This is an extension of
    https://go-review.googlesource.com/c/31662/
    to mark all the temporaries, not just the ssa-generated ones.
    
    Before-and-after ls -l `go tool -n compile` shows a 3%
    reduction in size (or rather, a prior 3% inflation for
    failing to filter temps out properly.)
    
    Replaced name-dependent "is it a temp?" tests with calls to
    *Node.IsAutoTmp(), which depends on AutoTemp.  Also replace
    calls to istemp(n) with n.IsAutoTmp(), to reduce duplication
    and clean up function name space.  Generated temporaries
    now come with a "." prefix to avoid (apparently harmless)
    clashes with legal Go variable names.
    
    Fixes #17644.
    Fixes #17240.
