* src/types.c (double): Add AIX and Darwin to the right TYPEDEF.
* src/powerpc/aix_closure.S: Remove the pointer to the outgoing
parameter stack.
* src/powerpc/darwin_closure.S: Likewise.
* src/powerpc/ffi_darwin.c (ffi_prep_args): Handle structures
according to the Darwin/AIX ABI.
(ffi_prep_cif_machdep): Likewise.
(ffi_closure_helper_DARWIN): Likewise.
Remove the outgoing parameter stack logic. Simplify the evaluation
of the different CASE types.
(ffi_prep_clousure): Avoid the casts on lvalues. Change the branch
statement in the trampoline code.
