I think the test was meant to test requests to 'localhost:80' instead
of 'localhost:80:80'. It passes even with 'localhost:80:80' because
net.SplitHostPort fails inside useProxy. Please comment if you want to
leave old 'localhost:80' is the list too to check old code path.

This CL introduces new methods for 'context' type, so we can
manipulate its values in an architecture independent way.
Use new methods to replace both 386 and amd64 versions of
dosigprof with single piece of code.
There is more similar code to be converted in the following CLs.
Also remove os_windows_386.go and os_windows_amd64.go. These
contain unused functions.

Rather than detecting vfp support via catching SIGILL signals,
parse the contents of /proc/cpuinfo.
As the GOARM values for NaCl and freebsd are hard coded, this parsing
logic only needs to support linux/arm.
This change also fixes the nacl/arm build which is broken because the
first stage of nacltest.bash is executed with GOARM=5, embedding that
into 5g.
The second stage of nacltest.bash correctly detects GOARM=7, but this is
ignored as we pass --no-clean at that point, and thus do not replace
the compiler.
Lastyly, include a fix to error message in nacltest.bash

CL 2118 makes the assumption that all references to runtime.tlsg
should be accompanied by a declaration of runtime.tlsg if its type
should be a normal variable, instead of a placeholder for TLS
relocation.
Because if runtime.tlsg is not declared by the runtime package,
the type of runtime.tlsg will be zero, so fix the check in liblink
to look for 0 instead of STLSBSS (the type will be initialized by
cmd/ld, but cmd/ld doesn't run during assembly).

Considerable rewriting of the parser and assembler (code generator)
but it's simpler and shorter now. The internal Addr type is gone; so
is the package that held it. Parsing of operands goes directly into
obj.Addrs now.
There is a horrible hack regarding register pairs. It uses the Class
field to store the second register since it needs _some_ place to
put it but none is provided in the API. An alternative would be nice
but this works for now.
Once again creates identical .6 and .8 files as the old assembler.

"go test -v" buffers output if more than one package is
being tested to avoid mixing the outputs from multiple
tests running in parallel. It currently enables streaming

It is ok to stream output from multiple tests if we know

testKillProcess() tries to build and run the Go equivalent

since the Go compiler is not available on the targets. This
change embeds the "sleep 1" functionality within the "os.test"

This change is an implementation of the signal
runtime and os/signal package on Plan 9.
Contrary to Unix, on Plan 9 a signal is called
a note and is represented by a string.
For this reason, the sigsend and signal_recv
functions had to be reimplemented specifically
for Plan 9.
In order to reuse most of the code and internal
interface of the os/signal package, the note
strings are mapped to integers.

Ideally, those methods should return a copy of the Addr, but
due to the Go 1 API guarantee, we cannot make that change now:
there might exist client code that uses the returned Addr as

of the method returns the same pointer. Changing this behavior
will lead to hidden behaviour change in those programs.
