Fix small bugs:

- Make sure cmd_obj & cmd_obj_sp contain a valid objects before attempting to 
dereference, in CommandObjectCommandsAlias::Execute and 
CommandInterpreter::HandleCommand.

- Modify CommandInterpreter::GetCommandSPExact to properly handle
multi-word command inputs.

Changed:
	SBValue LookupVarInScope (const char *name, const char *scope);
to
	SBValue FindValue (const char *name, ValueType value_type);

The latter makes it possible to not only find variables (params, locals, globals, and statics), but we can also now get register sets, registers and persistent variables using the frame as the context.

 - Don't perform the 'if condition hoisting' xform on certain

This re-fixes "example 7", without breaking the world hopefully.

first, it can kick in on blocks whose conditions have been
folded to a constant, even though one of the edges will be
trivially folded.

second, it doesn't clean up the "if diamond" that it just 
eliminated away.  This is a problem because other simplifycfg
xforms kick in depending on the order of block visitation,
causing pointless work.
