go/exact: future-proof API: permit setting precision limit

Added a prec parameter to MakeFromLiteral (which currently must
always be 0). This will permit go/types to provide an upper limit
for the precision of constant values, eventually. Overflows can be
returned with a special Overflow value (very much like the current
Unknown values).

This is a minimal change that should prevent the need for future
backward-incompatible API changes.

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.
