This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.

Fixes#9732Fixes#9819
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

This CL introduces the bootstrap requirement that in order to
build the current release (or development version) of Go, you
need an older Go release (1.4 or newer) already installed.
This requirement is the whole point of this CL.
To enforce the requirement, convert cmd/dist from C to Go.
With this bootstrapping out of the way, we can move on to
replacing other, larger C programs like the Go compiler,
the assemblers, and the linker.
See golang.org/s/go15bootstrap for details.
