getVarInfo() now always returns a variable with a location and scope. To opt out of this change, getVarInfo(false) returns an incomplete variable. This can be used to work around bugs, but should only really be used for printing. The complete var info will also contain the type, except for debug_values, as its type depends on another instruction, which may be inconsistent if called mid-pass. All locations in debug variables are now also stripped of flags, to avoid issues when comparing or hashing debug variables.
