[Bug tree-optimization/38789] [4.4 Regression] __builtin_constant_p appears to eveluate to true for non-constant arguments.

I wouldn't consider this a bug.  It's similar to

inline void foo(int i) { if (__builtin_constant_p (i)) you_loose(); }

void bar()
{
  foo (1);
  foo (2);
}

where the code is duplicated twice and both cases are constant.
