[Bug c/23665] [3.4 Regression] ICE in convert_move with -O3 (ok at -O2)

Problem of the C frontend using the first decl with int arg
and the inliner expecting to have a double in unit-at-a-time mode, -O1
-funit-at-a-time:

inline double func();

int main(void)
{
    double d = func(42);
    return 0;
}

inline double func(double arg)
{
    return arg * 2.0;
}

src/tests/pr23665.c: In function `main':
src/tests/pr23665.c:10: internal compiler error: in convert_move, at expr.c:563
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

We're probably confusing the two decls.  I guess we will not fix this for 3.4.
