Fix code so that a SkipUntil will ignore semicolons when skipping a
function body.  This keeps the brace count accurate to prevent
additional errors.  Also, moved the caret from the brace to the function
name.

Code:
class F{ int Foo{ return 1; } };

Fixed error:
parameters.cc:1:14: error: function definition does not declare parameters
class F{ int Foo{ return 1; } };
             ^
1 error generated.

Old errors:
parameters.cc:1:17: error: function definition does not declare parameters
class F{ int Foo{ return 1; } };
                ^
parameters.cc:1:30: error: expected ';' after class
class F{ int Foo{ return 1; } };
                             ^
                             ;
parameters.cc:1:31: error: expected external declaration
class F{ int Foo{ return 1; } };
                              ^
3 errors generated.
