This pragma cancels the effect of go:nowritebarrierrec. This is useful in the scheduler because there are places where we enter a function without a valid P (and hence cannot have write barriers), but then obtain a P. This allows us to annotate the function with go:nowritebarrierrec and split out the part after we've obtained a P into a go:yeswritebarrierrec function.
