ffi: handle misaligned access for arith types.

The align feature won't work properly on some machines,
since the underlying get and put routines don't handle
misaligned access. We address that here.

* ffi.c (align_sw_get, align_sw_end, align_sw_put_end,
align_sw_put): New macros.
(ffi_i16_put, ffi_i16_get, ffi_u16_put, ffi_u16_get, ffi_i32_put,
ffi_i32_get, ffi_u32_put, ffi_u32_get, ffi_i64_put, ffi_i64_get,
ffi_u64_put, ffi_u64_get, ffi_short_put, ffi_short_get, ffi_ushort_put,
ffi_ushort_get, ffi_int_get, ffi_uint_put, ffi_uint_get, ffi_long_put,
ffi_long_get, ffi_ulong_put, ffi_ulong_get, ffi_float_put,
ffi_float_get, ffi_double_put, ffi_double_get, ffi_val_put, ffi_val_get,
ffi_wchar_put, ffi_wchar_get, ffi_sbit_put, ffi_sbit_get, ffi_ubit_put,
ffi_ubit_get): Insert macros to redirect the transfer to a temporary
aligned buffer if the pointer is misaligned.
