Breakpoint not hit on function that begins with for (;;).

[Kaz Kylheku]

I'm debugging a program in which a function looks like this:

type foo(args)
{
 foo (;;) {
   /* logic */
 }
 return ...;
}

If I set a breakpoint on the function using

(gdb) b foo

it is ignored. This is because the breakpoint is placed on the
first line, and that first line isn't considered to contain
any expressions!

In my experience with various line-oriented debuggers, if
a breakpoint is set on a line that doesn't map to any code,
the debugger should actually search through the successors of
that line until it finds something breakable.
