For code such as:

int f(int x) {
  if (int foo = f(bar)) {}
  return 0;
}

Clang produces the following error messages:

paren_imbalance.cc:2:19: error: use of undeclared identifier 'bar'
  if (int foo = f(bar)) {}
                  ^
paren_imbalance.cc:2:26: error: expected ')'
  if (int foo = f(bar)) {}
                        ^
paren_imbalance.cc:2:6: note: to match this '('
  if (int foo = f(bar)) {}
     ^

The second error is incorrect.  This patch will stop Clang from producing an error on parenthesis imbalance during error recovery when there isn't one.
