print_rtx_function: integrate dumping of the CFG into the insn chain
gcc/ChangeLog:
* function-tests.c: Include "print-rtl.h".
(selftest::test_expansion_to_rtl): Call print_rtx_function on the
function, and verify what is dumped.
* print-rtl-function.c (print_edge): New function.
(begin_any_block): New function.
(end_any_block): New function.
(can_have_basic_block_p): New function.
(print_rtx_function): Track the basic blocks of insns in the
chain, wrapping those that are within blocks within "(block)"
directives. Remove the "(cfg)" directive.
