linux-amd64-noopt broken by [dev.garbage] all: merge dev.cc into dev.garbage

[bui...@golang.org]

Change 606ec10a461b broke the linux-amd64-noopt build:
http://build.golang.org/log/33b5160dc878c6817ed6c25f2041712430c522b4

[dev.garbage] all: merge dev.cc into dev.garbage

The garbage collector is now written in Go.
There is plenty to clean up (just like on dev.cc).

all.bash passes on darwin/amd64, darwin/386, linux/amd64, linux/386.
