Re: patch to improve register preferencing in IRA and to *remove regmove* pass


Please change the .opt entries to

foptimize-register-move
Common Ignore
Does nothing. Preserved for backward compatibility.

and

fregmove
Common Ignore
Does nothing. Preserved for backward compatibility.

rather than removing them completely.  In general, when removing an option 
that's purely about optimizations rather than affecting the semantics of 
the user's source code, it's best to leave it behind as an ignored option 
like that.
