Suppose we have the following type

struct S {
   union {
       int            i1;
       unsigned u1;
   union {
       int            i2;
       unsigned u2;
Current revision makes it impossible to evaluate it using MI, because MI assigns '??' as variable name to each of the unnamed unions after "-var-list-children" command. Also '??' incorrectly goes to 'exp' field which is treated by IDE as a structure field name and is displayed in watch window. 

The patch fixes this returning empty string as type name for unnamed union and assigning $N to variable name, where N is the field number in the parent entity.
