Austin Clements 7e343134d3 cmd/compile: compiler support for buffered write barrier

This CL implements the compiler support for calling the buffered write
barrier added by the previous CL.

Since the buffered write barrier is only implemented on amd64 right
now, this still supports the old, eager write barrier as well. There's
little overhead to supporting both and this way a few tests in
test/fixedbugs that expect to have liveness maps at write barrier
calls can easily opt-in to the old, eager barrier.

This significantly improves the performance of the write barrier:

name             old time/op  new time/op  delta
WriteBarrier-12  73.5ns ±20%  19.2ns ±27%  -73.90%  (p=0.000 n=19+18)

It also reduces the size of binaries because the write barrier call is
more compact:

name        old object-bytes  new object-bytes  delta
Template           398k ± 0%         393k ± 0%  -1.14%  (p=0.008 n=5+5)

GoParser           295k ± 0%         284k ± 0%  -3.62%  (p=0.008 n=5+5)

XML                404k ± 0%         395k ± 0%  -2.10%  (p=0.008 n=5+5)
[Geo mean]         704k              690k       -2.00%

name        old exe-bytes     new exe-bytes     delta
HelloSize         1.05M ± 0%        1.04M ± 0%  -1.55%  (p=0.008 n=5+5)

https://perf.golang.org/search?q=upload:20171027.1

(Amusingly, this also reduces compiler allocations by 0.75%, which,
combined with the better write barrier, speeds up the compiler overall
by 2.10%. See the perf link.)

It slightly improves the performance of most of the go1 benchmarks and
improves the performance of the x/benchmarks:

README.md

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

go run run.go

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

it is most naturally expressed using the test runner; or
it is also applicable to gccgo and other Go tool chains.
