Tweaks to print_rtx_function
gcc/ChangeLog:
* print-rtl-function.c (print_edge): Omit "(flags)" when none are
set.
(print_rtx_function): Update example in comment for...
* print-rtl.c (print_rtx_operand_code_r): In compact mode, print
non-virtual pseudos with a '%' sigil followed by the regno, offset
by (LAST_VIRTUAL_REGISTER + 1), so that the first non-virtual
pseudo is dumped as "%0".
