The parameter list given in general register 1 shall be aligned
on a quadword boundary. This test currently succeeds or fails
depending on the compiler version used and the accidential layout
of the function's stack frame.

CSST is defined as:
C(0xc802, CSST, SSF, CASS, la1, a2, 0, 0, csst, 0)
It means that the first parameter is handled by in1_la1().
in1_la1() fills addr1 field, and not in1.
Furthermore, when extract32() is used for the alignment check, the
third parameter should specify the number of trailing bits that must
be 0. For FC these numbers are:
FC=0 (word, 4 bytes): 2
FC=1 (double word, 8 bytes): 3
FC=2 (quad word, 16 bytes): 4
For SC these numbers correspond to the size:
SC=0: 0
SC=1: 1
SC=2: 2
SC=3: 3
SC=4: 4
