The RTQ (register-file to queue) instruction copies the contents of the specified
registers into a destination queue. The destination queue can be a local or a remote
one. The RTQ can become a delayed RTQ (or DTQ) according to the DTQ-offset (see the
LAL instruction). The burst length, remote communication offsets, and rtq-mode (i.e.,
whether delayed or not) are decoded from the last value stored by the LAL instruction.
The register-file is read via Port4.
Takes "burst lenght" cycles to execute.
