Log Message: ----------- 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).
