          more speed-ups possible by tightening up int version of JSImmediate

        1% improvement of SunSpider

        * kjs/JSImmediate.h: Eliminate the now-unneeded FPBitValues struct template.
        (KJS::JSImmediate::from): Overload for most numeric types; many types can
        do fewer branches and checks.
        (KJS::JSImmediate::getUInt32): Removed unneeded check for undefined.
        (KJS::JSImmediate::getTruncatedInt32): Ditto.
        (KJS::JSImmediate::getTruncatedUInt32): Ditto. There's no difference any more
        between getUInt32 and getTruncatedUInt32, so that's worth a rename and merge later.

        * kjs/grammar.y: Update since fromDouble is now just from.
        * kjs/nodes.h: Ditto.

        * kjs/value.h: (KJS::jsNumber): Overload for most numeric types.
