Message:

• Darin and I rewrote our implementation of the SimpleNumber class to store number bit patterns in their floating point formats.

My tweaks reviewed by Darin.

~1% speedup on JS iBench.

• kjs/internal.h: removed obsolete jsNumber declarations.
• kjs/math_object.cpp: (MathFuncImp::callAsFunction): changed KJS::isNaN to isNaN
• kjs/nodes.cpp: (PostfixResolveNode::evaluate): removed obsolete knownToBeInteger (PostfixBracketNode::evaluate): ditto (PostfixDotNode::evaluate): ditto (PrefixResolveNode::evaluate): ditto (PrefixBracketNode::evaluate): ditto (PrefixDotNode::evaluate): ditto (NegateNode::evaluate): ditto (valueForReadModifyAssignment): ditto
• kjs/number_object.cpp: removed obsolete comment
• kjs/operations.cpp: (KJS::equal): removed unnecessary isNaN checks (KJS::strictEqual): ditto (KJS::add): removed obsolete knownToBeInteger (KJS::mult): ditto
• kjs/operations.h: removed include of "value.h" to prevent circular reference
• kjs/simple_number.h: removed unnecessary #includes (KJS::SimpleNumber::make): see above (KJS::SimpleNumber::is): ditto (KJS::SimpleNumber::value): ditto
• kjs/string_object.cpp: (StringProtoFuncImp::callAsFunction): changed KJS::isNaN to isNaN
• kjs/ustring.cpp: removed unnecessary isNaN check (KJS::UString::toUInt32): ditto
• kjs/value.cpp: (KJS::jsNumber): removed obsolete jsNumber definitions (KJS::ConstantValues::init): NaN is no longer a ConstantValue (KJS::ConstantValues::clear): ditto (KJS::ConstantValues::mark): ditto
• kjs/value.h: removed obsolete knownToBeInteger (KJS::jsNaN): now returns a SimpleNumber (KJS::ValueImp::getUInt32): changed to account for NaN being a SimpleNumber (KJS::ValueImp::toBoolean): ditto (KJS::ValueImp::toString): changed to account for +/- 0.0 (KJS::jsZero): changed to reflect that SimpleNumber::make takes a double (KJS::jsOne): ditto (KJS::jsTwo): ditto (KJS::Number): removed obsolete non-double constructor declarations
