[lto] patch committed to fix calls and FUNCTION_DECLS

[Kenneth Zadeck <zadeck@naturalbridge.com>]

Bill Maddox sent me the following test case:

=============
unsigned fact(unsigned x)
{
  if (x == 0)
    return 1;
  else
    return x * fact(x - 1);
}

int
main()
{
  (void)fact(5);  /* dont' bother to print */
  return 0;
}
=============
Which i have processed with the following two commands:
=============
./xgcc -flto -c -O2 test/test.c -o test/test.o
./lto1 -O2 test/test.o -o test/test.o.o
=============
This patch fixes the first two problems that you would hit if you tried
this set of commands.
I am working on the third.
