[Bug c/23722] New: bad error recovery with if blocks and else

[pinskia at gcc dot gnu dot org]

An example:

int f()
{
  if (1)
  {
   return 1;
  else
  {
  }
}

the else should cause us to close the } block and we should only have one error message.  Right now we 
have two:
t.c: In function ‘f’:
t.c:6: error: expected expression before ‘else’
t.c:9: error: expected declaration or statement at end of input

The reason why I only want one error message is that we only have to fix this one place.
----
If we do:
int f()
{
  if (1)
  {
   return 1;
  else
  {
   }
  }
}

We get only one which is not fully correct as the block after the else was closed twice.
