New Cog VMs available

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3365

CogVM source as per VMMaker.oscog-eem.1332/r3365

Newspeak Cogit:

Fix the regression in implicit receiver sends caused by VMMaker.oscog-eem.1317

(fix to performance regression caused by using XCHG on x86).

The implicit receiver cache uses SendNumArgsReg to refer to the cache object.

Hence we must use TempReg for genPushRegisterArgsForNumArgs: in this case.

So refactor to genPushRegisterArgsForNumArgs:scratchReg:, passing either

TempReg or SendNumArgsReg as approprate.

best,

Eliot
