Cogits.
Fix bad bug in pc mapping of methods containing primitives.
methodUsesPrimitiveErrorCode:header: used the initialPC inst var, rather than
deriving the initialPC of the method parameter.  initialPC is stale/over ripe,
being that of the last JITTED method.  So many methods containing primitives
get their PC mapping wrong.  We haven't noticed this much because primitives
typically succeed.  Nuke an obsolete version of the method.

Have the Spur immutability store generators voidReceiverOptStatus, since with
immutability, stores are suspension pioints (when an immutability check fails)
and so receiverResultReg cannot be assumed to be live after a store.

Remove ssAllocateRequiredRegMask:upThrough:, inlining it into its callers,
ssAllocateCall/RequiredReg:... et al.

Clean up the computation of the register mask in SistaCogit>>genForwardersInlinedIdenticalOrNotIf: et al.
