Before/after, best of 3:
json.BenchmarkCodeEncoder  10  183495300 ns/op  10.58 MB/s

json.BenchmarkCodeEncoder  10  133025100 ns/op  14.59 MB/s

But don't get too excited about this.  These benchmarks, while
stable at any point of time, fluctuate wildly with any line of
code added or removed anywhere in the path due to stack splitting
issues.

It's currently much faster, though, and this is the API that
doesn't allocate so should always be faster in theory.

The plan is to make 'go test' replace gotest entirely, so it
cannot refer to gotest's godoc.  Instead, copy gotest's
documentation in as three different help messages:
'go help test', 'go help testflag', and 'go help testfunc'.

I have included a few important microbenchmarks,
but the overall intent is to have mostly end-to-end
benchmarks timing real world operations.

The jsondata.go file is a summary of agl's
activity in various open source repositories.
It gets used as test data for many of the benchmarks.

Everything links into one binary (even the test data)
so that it is easy to run the benchmarks on many
computers: there is just one file to copy around.

emitted by inlining (breaking strconv ftoa alloc count unittest) and is better in any case.

This change guarantees that whether the line ending convention
when the source is created includes carriage returns is irrelevant
to the value of the string. See issue 680.

clean is gone; all the intermediate files are created
in a temporary tree that is wiped when the command ends.

Not using go/build's Script because it is not well aligned
with this API.  The various builder methods are copied from
go/build and adapted.  Probably once we delete goinstall
we can delete the Script API too.

I realize I didn't send the tests in last time.  Anyway, I added
a test that knows too much about the package's internal structure,
and I'm not sure whether it's the right thing to do.

The obvious fix is breaking the build in non-obvious ways.
Reverting while waiting for the correct fix, if any is needed.
