The introduction of TCGV_EQUAL and not op is slightly broken.

Some fixes for TCG debugging

This fixes a few things after Paul's improvements for TCG debugging:

- change TCGv_i64 field name to something different from
    TCGv_i32
  - fix things in tcg that the above change made visible.

arm: Don't potentially overwrite input registers in add2, sub2.

According to malc TCG will often genereate an add2/sub2/mul2 with low
half of the output in the same register as high half of one of the
inputs, so account for that.
