cmd/internal/ssa: utility functions to make Funcs
Adds a more convenient way to define Funcs for testing.
For instance,
b1:
v1 = Arg <mem> [.mem]
Plain -> b2
b2:
Exit v1
b3:
v2 = Const <bool> [true]
If v2 -> b3 b2
can be defined as
fun :=Fun("entry",
Bloc("entry",
Valu("mem", OpArg, TypeMem, ".mem"),
Goto("exit")),
Bloc("exit",
Exit("mem")),
Bloc("deadblock",
Valu("deadval", OpConst, TypeBool, true),
If("deadval", "deadblock", "exit")))
Also add an Equiv function to test two Funcs for equivalence.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
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.
