This commit adds the following instructions to support the new SSA backend for s390x: 32-bit operations: ADDW SUBW NEGW FNEGS Conditional moves: MOVDEQ MOVDGE MOVDGT MOVDLE MOVDLT MOVDNE Unordered branches (for floating point comparisons): BLEU BLTU Modulo operations: MODW MODWU MODD MODDU The modulo operations might be removed in a future commit because I'd like to change DIV to produce a tuple once the old backend is removed. This commit also removes uses of REGZERO from the assembler. They aren't necessary and R0 will be used as a GPR by SSA.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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 file). 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-source.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 https://golang.org/doc/install or doc/install.html for more details.
