New Revision: 43130
URL: https://trac.parrot.org/parrot/changeset/43130

Log:
[ops] Made callmethodcc op skip creating a RetContinuation when invoking an NCI
method, as it's unnecessary and expensive and trunk doesn't do it, because it's
the invokee's responsibility to create the RetCont.  This improves branch
performance by 2.499% on fib4.pir.
