  CogVM source as per VMMaker.oscog-eem.3307/VMConstruction-Plugins-OSProcessPlugin.oscog-eem.76

Implement a machine code primitive for primitiveHighResClock on 64-bit platforms.
This is faster than the fast-call interpreter primitive by 15% on x86_64 and by
480% on ARMv8 (Apple M1).

Have compilePrimitive use methodOrBlockNumArgs rather than argumentCountOf: methodObj.

Fix the type of semaIndices.  This should be int. unsigned char risks corruption
if there are more than 256 external semaphores, which could be the case in a
very complex application.
Fix a few sends of stackIntegerValue: that were not followed by the obligatory
interpreterProxy failed check.  I lost patience/time, but this really should be
done.  In all VMs, proceeding after a primitive has failed without checking for
primitive failure can have disastrous effects (arguments are popped off the
stack that shouldn't be).
