Prepare to push version 1.2.4 to trunk.

ChangeLog

+2009-05-18: Version 1.2.4
+
+        Improved performance of floating point number allocation for ARM
+        platforms.
+
+        Fixed crash when using the instanceof operator on functions with
+        number values in their prototype chain (issue 341).
+
+        Optimized virtual frame operations in the code generator to speed
+        up compilation time and allocated the frames in the zone.
+
+        Made the representation of virtual frame and jump targets in the
+        code generator much more compact.
+
+        Avoided linear search for non-locals in scope code when resolving
+        variables inside with and eval scopes.
+
+        Optimized lexical scanner by dealing with whitespace as part of
+        the token scanning instead of as a separate step before it.
+
+        Changed the scavenging collector so that promoted objects do not
+        reside in the old generation while their remembered set is being
+        swept for pointers into the young generation.
+
+        Fixed numeric overflow handling when compiling count operations.

         Fixed bug in reporting of out-of-memory situations.
 
         Introduced hidden prototypes on certain builtin prototype objects
         such as String.prototype to emulate JSC's behavior of restoring
         the original function when deleting functions from those prototype
         objects.
 
         Fixed crash bug in the register allocator.

         Improved debugger support by allowing nested break points and by
         dealing with stack-overflows when compiling functions before
         setting break points in them.

         Initial export.
