[Bug middle-end/32492] [4.3 Regression] attribute always_inline -> sorry, unimplemented: recursive inlining

[pinskia at gcc dot gnu dot org]

I can find a testcase, if we change where we generate the promotion at the RTL
expansion time, worse code.
Simple testcase:

int f(int b, char a)
{
  if (b)
    a = 1;
  g(a);
}

You can see the difference by looking 3.4 vs 4.2's code generation :).
