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.
