Accept more floating point constant expressions

Browse Source 
the rules for constant expressions in static initializers are more
relaxed than for integer constant expressions.  We need to accept
0.0/0.0 in static initializers (in non-static initializers the potential
exceptions need to be raised though, so no translation-time calculation
then).
