VMMaker 4.7.2

Reference <http://lists.squeakfoundation.org/pipermail/vm-dev/2011-August/009006.html>
Fix NewObjectMemory>>newObjectHash to use shiftForWord rather than bytesPerWord (check to ensure corresponding fix in oscog).

Reference Mantis 6987: signed32BitValueOf:, signed64BitValueOf: etc. broken
Discussion at <http://lists.squeakfoundation.org/pipermail/vm-dev/2011-July/008905.html>

Fix #signed32BitValueOf: and #signed64BitValueOf: which are reported broken for some optimizing C compilers. Cast to unsigned integer to prevent undefined behavior on arithmetic overflow.

Add InterpreterPrimitivesTest to provide some coverage of #signed64BitValueOf:

Follow up required - Test to verify fix on problematic compilers. Merge with oscog.
