coverage: Use SpanMarker to mark the full condition of if !

Browse source 
When MIR is built for an if-not expression, the `!` part of the condition
doesn't correspond to any MIR statement, so coverage instrumentation normally
can't see it.

We can fix that by deliberately injecting a dummy statement whose sole purpose
is to associate that span with its enclosing block.
