runtime: make garbage collector faster by deleting code Suggested by Sanjay Ghemawat. 5-20% faster depending on the benchmark. Add tree2 garbage benchmark. Update other garbage benchmarks to build again. R=golang-dev, r, adg CC=golang-dev https://golang.org/cl/5530074 2012-01-10 20:49:11 -07:00			`tree2\`

Beyond that we will need to so something more sophisticated, like have each core hand off to the next one, around a circle. Even so, the code is a good checkpoint; for now we'll limit the number of gc procs to at most 2. R=dvyukov CC=golang-dev https://golang.org/cl/4641082 2011-09-30 07:40:01 -06:00			`time ./$*.out`
