      cleanup special tarval and Unknown usage · af666143
      Matthias Braun authored
      This commit does:
      - Remove tarval_reachable+tarval_unreachable, dataflow analysis rather
        use top/bottom instead of other special values.
      - Rename tarval_undefined to tarval_unknown as it corresponds to the
        Unknown node (=a value which we don't know)
      - Remove predefined tarval_top/tarval_bottom from tv.h and place the
        defines into combo.c
      - Change compute_XXX constant folding functions to return tarval_unknown
        instead of tarval_bad if folding failed
      - compute_Unknown in combo results in tarval_bottom == tarval_unknown
        this eliminates strange special cases in the Cond/Switch rules and the
        now unnecessary cprop_X list.

      remove incorrect Unknown optimisations · 67add5ec
      Matthias Braun authored
      Optimizing arithmetic with Unknown nodes to a new Unknown node is
      illegal unless you can prove that the original Unknown node has no
      other users.
