Changes include:
1. enable compiler option -race for arm64
2. add runtime/race_arm64.s to manage the calls from Go to the compiler-rt runtime
3. change racewalk.go to call racefuncenterfp instead of racefuncenter on arm64 to
allow the caller pc to be obtained in the asm code before calling the tsan version
4. race_linux_arm64.syso comes from compiler-rt which just supports 48bit VA, compiler-rt
is fetched from master branch which latest commit is 3aa2b775d08f903f804246af10b

Recognize NetBSD in:
- go/internal/work/init.go
- race.bash
- runtime/race/race.go
Add __ps_strings symbol in runtime/cgo/netbsd.go as this is
used internally in the TSan library for NetBSD and used for
ReExec().
Tested on NetBSD/amd64 v. 8.99.12.
Around 98% tests are passing for the ./race.bash target.

This adds the support to enable the race detector for ppc64le.
Added runtime/race_ppc64le.s to manage the calls from Go to the
LLVM tsan functions, mostly converting from the Go ABI to the
PPC64 ABI expected by Clang generated code.
Changed racewalk.go to call racefuncenterfp instead of racefuncenter
on ppc64le to allow the caller pc to be obtained in the asm code
before calling the tsan version.
Changed the set up code for racecallbackthunk so it doesn't use
the autogenerated save and restore of the link register since that
sequence uses registers inconsistent with the normal ppc64 ABI.
Made various changes to recognize that race is supported for
ppc64le.
Ensured that tls_g is updated and accessible from race_linux_ppc64le.s
so that the race ctx can be obtained and passed to tsan functions.
This enables the race tests for ppc64le in cmd/dist/test.go and
increases the timeout when running the benchmarks with the -race
option to avoid timing out.

I'm tired of having to remember it on every command.
Rebuilding everything is the wrong default.
This CL updates the build script, but the builders may
(or may not) need work, depending on whether they
rebuild using the test command (I doubt it).

The one in misc/makerelease/makerelease.go is particularly bad and
probably warrants rotating our keys.
I didn't update old weekly notes, and reverted some changes involving
test code for now, since we're late in the Go 1.5 freeze. Otherwise,
the rest are all auto-generated changes, and all manually reviewed.

The wildcard 'std' is defined in documentation to be all the packages
in the Go standard library. It has also historically matched commands
in the main repo, but as we implement core commands in Go, that
becomes problematic. We need a wildcard that means just the library,
and since 'std' is already documented to have that definition, make it so.
Add a new wildcard 'cmd' for the commands in the main repo ($GOROOT).
Commands that want both can say 'std cmd' (or 'cmd std') to get the
effect of the old 'std'.
Update make.bash etc to say both std and cmd most of the time.
Exception: in race.bash, do not install race-enabled versions of
the actual commands. This avoids trying to write binaries while
using them, but more importantly it avoids enabling the race
detector and its associated memory overhead for the already
memory-hungry compilers.

Fixes#5537.
To avoid `go install -v race std` replacing cmd/cgo with a race enabled version and another package trying to build a cgo enabled package, always build cmd/cgo race enabled before doing the rest of the build.
