Log Message:
  -----------
  CogVM source as per VMMaker.oscog-eem.3242
General:
Tiny tweak to eliminate duplicate strlens in methodHasPrimitiveInPrimTracePlugin:
Slang:
Abstract checking for names defineAtCompileTime: so that the VMPluginCodeGenerator
can ask the pluginClass and ence that BytesPerWord is considered defined at
compile time, except within the ThreadedFFIPlugins.
ThreadedFFIPlugin:
Always do inline ffiCall:ArgArrayOrNil:NumArgs:. We should err on the side of
speed.  The code size shouldn't affect icache performance because the
primitiveCalloutWithArgs path is used very rarely in practice.
Now that ffiCall:ArgArrayOrNil:NumArgs: is always inlined, also inline
ffiReturnType:, avoiding unnecessary duplication.
Have all ThreadedFFIPlugins assign BytesPerWord in their initialize methods,
to inline positiveMachineIntegerFor: et al.  Override
InterpreterPlugin class>>#shouldGenerateDeadCode since these are very
platform-specific and the dead code decision well under control.
Fix nonRegisterStructReturnIsViaImplicitFirstArgument for RiscV64FFIPlugin.
Make it inline always on all of them, along with a few others.
