Something to know about Java is that how FP operations are implemented
depends on the context. In a `strictfp' context certain rules must be
followed. In other contexts, the rules are more lenient and we can do
more optimizations. This might matter most for RTL generation; I
don't know.
Currently gcj ignores strictfp. Obviously we will eventually want to
change this.
