Conditional branches sometimes have a likely/unlikely bit attached to them.

	0x008c 00140 (s.go:7)	JLT	$0, 55

$0 means the branch is unlikely, $1 means the branch is likely.
There's really no reason why the assembly output should show these. It's an artifact of instruction reordering in the obj library that is now gone. We should just stop setting these marks when generating Progs.

See #15837
