math/big: multi-precision Floats (starting point)

Implemented:
- +, -, *, /, and some unary ops
- all rounding modes
- basic conversions
- string to float conversion
- tests

Missing:
- float to string conversion, formatting
- handling of +/-0 and +/-inf (under- and overflow)
- various TODOs and cleanups

With precision set to 24 or 53, the results match
float32 or float64 operations exactly (excluding
NaNs and denormalized numbers which will not be
supported).

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.
