  Log Message:
  -----------
  PeepholeOpt: Do not skip reg_sequence sources with subregs

Contrary to the comment, this particular code is not responsible
for handling any composes that may be required, and unhandled cases
are already rejected later. Lift this restriction to permit composes
and reg_sequence subregisters later.
