For reference, here are the changes to patch 8a to update it to the
new syntax.

I'm assuming that this (and the changes to the various dumpfiles in
patches 8b-8d) count as "obvious".

gcc/ChangeLog:
	* read-rtl-function.c (lookup_reg_by_dump_name): Rework to expect
	regno wrapped in '<' and '>' rather than with a '%' prefix.
	(selftest::test_parsing_regnos): Update for above change.
