PR rtl-optimization/42216
* regrename.c (create_new_chain): New function, broken out from...
(scan_rtx_reg): ... here. Call it. Handle the case where we are
appending a use to an empty chain.
(build_def_use): Remove previous changes that convert OP_INOUT to
OP_OUT operands; instead detect the case where an OP_INOUT operand
uses a previously untracked register and create an empty chain for
it.
