so we have to account for it. This insn is used in the 32-bit ABI
when calling a function that returns a non zero-sized structure. The
64-bit ABI doesn't have it. Be careful to have this test be the same
as that used on the call. The exception here is that when
sparc_std_struct_return is enabled, the psABI is followed exactly
and the adjustment is made by the code in sparc_struct_value_rtx.
The call emitted is the same when sparc_std_struct_return is
present. */
