At your convenience, we aren't in a hurry. Patch is OK if you update
/* Simplify the code below by rewriting things to reflect
matching constraints. Also promote OP_OUT to OP_INOUT
in predicated instructions. */
in build_def_use, something like "... but only for register operands that are
already tracked, so that we can create a chain when the first SET makes a
register live".
