I am wondering whether we are using the data_alignment correctly.

Currently we are adjusting the offset in unwind_frame. Assuming
state->dataAlign always has to be used. But the DWARF spec says that some
DW_CFA operations (DW_CFA_def_cfa and DW_CFA_def_cfa_offset) take a
non-factored offset. So we should factor the offset in processCFI() instead
only when needed and not adjust in unwind_frame.
