Hi,

Once the corresponding CGEN changes are approved, I would like to commit 
this patch which brings the sh64 simulator up to date. The CGEN changes 
in question were to allow the generation of a SID simulator with full 
pipeline modelling and to add support for some unsupported insns. The 
effects on the sh64 simulator are as follows:

1) Add code to support additional CGEN machines which were added.
2) Add code to support newly supported insns.
3) Regenerate all CGEN-generated source files. Some bit rot in the 
invocation of CGEN was fixed here in the process.

Pending approval of the corresponding CGEN changes, is this ok to commit?

Dave
