92922be83c0b4b98d50f24cc3a1e7cc0a1b5741a Remove skip_txfm optimization.
Commit 0d6980d7a1caa592058f8d5d618b012c160772f7 removed some use
of the skip_txfm optimization, and the rest are not productive.
The current use of this optimization is only used with --good
and --cpu-used >= 3, however the overhead of this is higher than the
speedup it yields.
Removing this, and subsequently simplifying model_rd_for_sb yields
a net encoder speedup:
--cpu-used=0 ~1.5% faster
--cpu-used=3 ~2.0% faster
The code simplification is also significant.
