4e86afb85f * mn10300.igen: Fix Z bit for addc and subc instructions. 
Minor fixes in multiply/divide patterns.

start-sanitize-am33
        * am33.igen: Fix Z bit for addc Rm,Rn and subc Rm,Rn.  Various
        fixes to 2 register multiply, divide and mac instructions.  Set
        Z,N correctly for sat16.  Sign extend 24 bit immediate for add,
        and sub instructions.

        * am33.igen: Add remaining non-DSP instructions.

baa83bcc80 * interp.c: Improve hashing routine to avoid long list 
traversals for common instructions.  Add HASH_STAT support.
        Rewrite opcode dispatch code using a big switch instead of
        cascaded if/else statements.  Avoid useless calls to load_mem.

8517f62b16 Ref gdb/11763 - can't stop a running simulator: 
o	Provide poll_quit callback to simulators
		so that they can poll for SIGINT on
		clueless OS's.

	o	Add sim_stop to simulators so that clients
		can request a halt (eg gdbtk's STOP button)
		Works for PPC!

	o	Re-arange remote-sim.c so that the
		hard work is moved from gdbsim_resume()
		to gdbsim_wait() (where it should be).
