print-rtl.c: use '<' and '>' rather than % for pseudos in compact mode

Browse Source 
gcc/ChangeLog:
	* print-rtl.c (rtx_writer::print_rtx_operand_code_r): For
	non-virtual pseudos in compact mode, wrap the regno in '<' and '>'
	rather than using a '%' prefix.
	* rtl-tests.c (selftest::test_dumping_regs): Update for above change.
