According to the PPC64 Linux ABI, the following functions argument should be
passed in gprs.  Instead, I find that x1 is passed in an fpr.

typedef struct { double d; } sd;
typedef struct { double d1, d2; } sd2;
double f1 (sd x1) { return x1.d; }
double f2 (sd2 x2) { return x2.d1; }

This is another symptom of gcc's habit of treating a single component struct as
if the component were not wrapped in "struct { }".

The ABI will be changed to reflect GCC behavior.  GCC's behavior will not be
changed.
