This CL adjusts code referring to src/pkg to refer to src.
Immediately after submitting this CL, I will submit
a change doing 'hg mv src/pkg/* src'.
That change will be too large to review with Rietveld
but will contain only the 'hg mv'.
This CL will break the build.
The followup 'hg mv' will fix it.
For more about the move, see golang.org/s/go14nopkg.

Also rename the go parser test to GoParse so it doesn't grab the globally useful Parse name.

If we're benchmarking 8g, use gcc -m32.
If we're benchmarking 6g, use gcc -m64.

-lm must come after the source file, versions of gcc insist this strict order.
On standard compliant systems, we no longer need malloc.h for malloc.
Use pkg-config(1) to get correct glib cflags and libs.
Fix compiler warning in threadring.c and k-nucleotide.c.

Here is a static copy of the go/parser benchmark. I ended up using
fancy encodings because the original parser.go had a number of `s
scattered throughout which made it hard to embed the source directly.
Curiously on my laptop this benchmark always scores roughly 10% higher
than the standalone benchmark. This may be down to the generation of
the fasta data set triggering the cpu governor to raise the cpu speed.
However the benchmark is consistent with itself across multiple runs.

As discussed on golang-dev, reduce the size of the fasta
dataset to make it possible to run the go1 benchmarks on
small ARM systems.
Also, remove the 25m suffix from fasta data and Revcomp.

We can't depend on init() order, and certainly we don't want to
register all future benchmarks that use jsonbytes or jsondata to init()
in json_test.go, so we use a more general solution: make generation of
jsonbytes and jsondata their own function so that the compiler will take
care of the order.

Most significant in mandelbrot, from avoiding MOVSD between registers,
but there are others.

Surprise! The C code is using floating point values for its counters.
Its off the critical path, but the Go code and C code are supposed to
be as similar as possible to make comparisons meaningful.
It doesn't have a significant effect.

Moving panic out of line speeds up fannkuch almost a factor of two.
Changes to bitwhacking code affect mandelbrot badly.

Unexports runtime.MemStats and rename MemStatsType to MemStats.
The new accessor requires passing a pointer to a user-allocated
MemStats structure.
Fixes#2572.

Also delete gotest, since it's messy to fix and slated for deletion anyway.
A couple of things outside src can't be tested any more. "go test" will be
fixed and these tests will be re-enabled. They're noisy for now.
Fixes#284.

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.

Some tests are significantly faster (50%), a few are slower (up to 30%).
Fannkuch is confusing: parallel code is a little slower for gc, non-parallel and all gccgo runs are faster.

Interesting comparisons between old and new machine,
and relationship between gccgo and gc.
