[Bug middle-end/22347] Return value register not correctly computed for indirect function call

[rguenth at gcc dot gnu dot org]

I have a fix for the target dependent parts.  Only tree-tailcall stomps on
our feet yet.  I.e.

double __attribute__((sseregparm)) mysin(double);
double __attribute__((sseregparm)) (*mysinfp)(double) = mysin;
double bar(double x)
{
  return 1.0+mysinfp(x);
}

is fixed at -O0 and -O2, the original testcase passes at -O0 but fails at
-O2.
