Cuong Manh Le 6edd7971bb cmd/compile: optimize len check when make slice
In CL 226278, we did:

	if len < 0 { panicmakeslicelen }
	if len > cap { panicmakeslicecap }

But due to the fact that cap is constrained to [0,2^31), so it is safe
to do:

	if uint64(len) > cap {
	    if len < 0 { panicmakeslicelen() }
	    panicmakeslicecap()
	}

save us a comparison in common case when len is within range.

Passes toolstash-check.
