The testcases as written made assumptions about size_t and long
being invalid for use with "%u".

We only need some invalid type, so this patch converts them to
attempt a "const char *" with "%u", which should be invalid for

If a jump always falls through but that cannot be optimised away, like
is the case with the PowerPC bdnz insn if its jump target is the same as
the fallthrough, sched gets confused if it schedules some instructions
from before that jump instruction to behind it: it splits the
fallthrough branch, but the jump target isn't updated, and things fall
apart as in the PR.  This patch fixes it.

The second patch fragment makes -fsched-verbose=N work for N>=4; the
currently scheduled fragment can now contain a label.  Everything else
seems to work fine with that.

	* cfgrtl.c (rtl_split_edge): Also patch jump insns that jump to the
	fallthrough.
