/* Test AAPCS64 layout.
Test the comformance to the alignment and padding requirements.
B.4 If the argument type is a Composite Type then the size of the
argument is rounded up to the nearest multiple of 8 bytes.
C.4 If the argument is an HFA, a Quad-precision Floating-point or Short
Vector Type then the NSAA is rounded up to the larger of 8 or the
Natural Alignment of the argument's type.
C.12 The NSAA is rounded up to the larger of 8 or the Natural Alignment
of the argument's type.
C.14 If the size of the argument is less than 8 bytes then the size of
the argument is set ot 8 bytes. The effect is as if the argument
was copied to the least significant bits of a 64-bit register and
the remaining bits filled with unspecified values. */
