[RFA:] Fix breakage of manually building SID CPU

[Hans-Peter Nilsson <hans-peter.nilsson@axis.com>]

See dev.scm.  The recentlish (within the last years) enumeration
SID-SIMULATOR, split off from SIMULATOR, isn't handled in
dev.scm, causing the cload after load-sid to error.  It means my
how-to-repeat description for the SID-generator-problem with
cris.cpu at <URL:http://sourceware.org/ml/cgen/2004-q4/msg00015.html>
broke with the SID-SIMULATOR introduction.  I.e.:

(load "dev.scm")
(load-sid)
(cload #:arch "../../cpu/cris" #:options "with-scache" #:machs "crisv32")
(cgen-decode.cxx)

got, at the (cload ...):

Backtrace:
In dev.scm:
  84: 0  [error "unknown application:" SID-SIMULATOR]
  52: 1  (case APPLICATION ((UNKNOWN) (error "application not
loaded")) ...)
  33: 2  (let (# # # #) (letrec # #) (case APPLICATION # # ...))
In standard input:
   3: 3* [cload #:arch "../../cpu/cris" #:options "with-scache"
#:machs "crisv32"]

dev.scm:84:13: In procedure error in expression (error "unknown
application:" APPLICATION):
dev.scm:84:13: unknown application: SID-SIMULATOR
ABORT: (misc-error)

Which begs the question: how do people debug their new SID CPU
ports these days?

Maybe the fix is as simple as copying the SIMULATOR case?
A patch follows for that.  It works for the guile sequence
above.  With CGEN sources at the time of this writing, I no
longer get the error above or at the URL.  I haven't checked
whether the generated code is correct, though.

Ok to commit?

cgen:
	* dev.scm (cload) <SID-SIMULATOR>: New case, duplicated from
	SIMULATOR.
