Cog-eem.225:Spur Bootstrap:Update the prototypes and package patching forthe Float => Float,BoxedFloat64/SmallFloat64refactoring.Use collect:as: to simplify allMethodPrototypes.

Cog-eem.224:Fix SpurBootstrap>>allMethodPrototypes givenEsteban's reorganization.Make fillInPointerObjectWithPC:from: tolerate a nilmethod (for the MethodContext prototype).64-bit-ize the bootstrap, which involves:Fix findRequiredGlobals for the potentiallyUndeclared BoxedFloat64.Fix installableMethodFor:selector:className:isMeta:for up-to 64-bit Integer literals.Map SmallFloat64 to an immediateSubclass:.Make the prototype for fromIEEE32Bit: multiply by1.0 to reduce result to a SmallFloat64 if possible.Make recreateSpecialObjectsArray installBoxedFloat64 in place of Float.
VMMaker.oscog-eem.957:Fix regression in magnitude64BitIntegerFor:neg:Move dispdbg.h above cointerp.h & cogit.h in cogit.cotherwise NoDbgRegParms gets screwed up.Use asInteger instead of asUnsignedIntegerin followForwardingPointersInStackZone: sosimulation of Stack VM doesn't trigger the assert inasUnsignedInteger.Spur:Make instantiateClass:indexableSize: check forFloat instantiation, failing for other than 2 words.Rewrite 32-bit coalesce:and: to use the raw slotaccessors.  Implement 64-bit coalesce:and:.Simulator:Make printStackCallStackOf: accept contexts.
VMMaker.oscog-eem.961:Fix StackInterpreter>>isFloatObject: andprimitiveVMParameter to use isFloatInstance:.Fix simulation of primitiveSmallFloatTruncated.

VMMaker.oscog-eem.960Add some SmallFloat64 tests.Hence fix isSmallFloatValue: for simulation.

VMMaker.oscog-eem.959:
Reimplement primitiveCopyObject to work for bothpointer and bits objects.  This to support a goodObject>>clone for Spur.Fix shortPrint: and simulated use of dbgFloatValueOf:,moving it to the ObjectMemory hierarchy.Fix Spur's isWordsOrBytes[NonImm]:.

VMMaker.oscog-eem.958:
Fix simulation of sizeof: in InterpreterPlugins
Cog-eem.228Spur 32- to 64-bit bootstrap:Remember to install SmallFloat64 in the first classtable page at smallFloatTags, replacing the entryfor SmallInteger in the 32-bit system (because in32-bits SmallInteger can have tag 1 or tag 3).

Cog-eem.227:...and classify those puppies:Behavior>>#isCompiledMethodClass is unclassifiedSmallFloat64>>#clone is unclassified

Cog-eem.226:Spur Bootstrap:Provide missing SmallFloat64 clone override andprovide a consistent comment for SmallInteger's.Provide an Object>>clone that copes with need toGC when memory is low.
