[PATCH] Add C/C++ attribute 'optnone'

[Robinson, Paul]

Compiling with -Os or -Oz will set OptimizeForSize or MinSize; 'optnone' should work regardless.
If it's easy to distinguish when the Attribute comes from a command-line option instead of in-source, at the point where we're ready to complain, then I'm okay with complaining.  (Sema is not exactly my strong suit.)

What's the argument for allowing optnone to override minsize, rather than rejecting the case where they appear together? (I'm not saying this is inappropriate, but I'd like to make sure this is the right choice.)

Adds a new 'optnone' function attribute that maps directly to the LLVM IR 'optnone' attribute.
