CL 56120043 fixed TLS handling on ARM after the introduction of liblink but left older ARM processors broken. Before liblink, the MRC instruction was replaced with a fallback on older ARMs. CL 56120043 removed that, because the rewrite matched bit patterns on the AWORD pseudo-instruction and could therefore change unrelated AWORDs that happened to match. This CL adds an AMRC instruction to encode both MRC and MCR previously encoded as AWORDs. Then, in liblink, the AMRC instructions are either rewritten to AWORD, or, on goarm < 7, replaced with a branch to the fallback. ./all.bash completes successfully on an ARMv7 with either GOARM=7 or GOARM=5. I have verified that the fallback is indeed present in both runtime.save_gm and runtime.load_gm when GOARM=5 but not when GOARM=7. If all goes well, this should fix the armv5 builders.

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
