VMMaker.oscog-eem.988:
Fix isSmallFloatValue: for the low boundary case.Eliminate an obsolete type declaration.

VMMaker.oscog-eem.987:Fix generateIsIntegerObject:on:indent: for 64-bit Spur.Make primitiveFloatAt support immedate floats.Fix the regression of breakmnu (breakSelectorLengthmust be initialized early).Make shortPrintOop: primnt immediate floats.Fix the stack page size for 64-bits.Add boundary cases for isSmallFloatValue:

VMMaker.oscog-eem.986:Spur:Eliminate the erroneous and confusingsetRawNumSlotsOf:to: and setOverflowNumSlotsOf:to:.Use rawNumSlotsOf:put: & rawOverflowSlotsOf:put:which match the getters.  Hence fix 64-bit compaction.Simulator:Don't warn of MNU redirection in doits.

VMMaker.oscog-eem.985:Fix slip in unreachableMethods.Print first field of free chunks in printOop:if on Spur.
VMMaker.oscog-eem.991:The fetchLong32:ofFloatObject: indirection shouldne marked inline to avoid changing generatedsource too much.

VMMaker.oscog-eem.990:Fix bitInvert32 for 64-bits.  Now window bordercolours are correct in the 64-bit Spur Stack linux VM.Cast a left shift to long if in the 64-bit interpretercode.Fix printFreeListHeads

VMMaker.oscog-tpr.989:
Update the ScratchPlugin bilinear scaling prim to include the correct alpha channel value for non-transparent output pixels.
