a6971f4c11 cmd/compilebench: use go command in goroot, not environment 
The "go" command is a random "go" in the environment, not
necessarily the one under test.  Use the go command in the
goroot we're testing.

This CL removes the need to add $GOROOT/bin to your path
before running compilebench.

518248cfad cmd/compilebench: add -pkg flag to compile a single package 
Sometimes, as with CL 41493, or when investigating
a reported issue, there's a package of interest
that is not part of the standard compilebench suite.
Add a -pkg flag to allow easy access to the compilebench
set of goodies (allocs, object file stats) without
having to edit and reinstall compilebench itself,
which is what I have been doing.

24acc66eab cmd/compilebench: put in correct subdirectory 
Apparently there was a typo during initial import,
and compilebench was placed at the top level,
rather than in the cmd subdirectory. Oops. Fix that.
