  CogVM source as per VMMaker.oscog-eem.3254

Further simplify ThreadedFFIPlugin>>ffiIntegerValueOf:; given that it now
answers 64-bit results we can subsume all the isLargePositiveIntegerObject:,
isLargeNegativeIntegerObject: & signedMachineIntegerValueOf: cases by a single
signed64BitValueOf: case.

Simplify signed64BitValueOf:; it can answer the magnitude related result
expression directly, and there is no need for the 64-bit magnitude test
unless the byte length is 8 (i.e. > 4).
