[IA64] Sanitize assembler code for ia64_sal_os_state
struct ia64_sal_os_state has three semi-independent sections. The code
in mca_asm.S assumes that these three sections are contiguous, which
makes it very awkward to add new data to this structure. Remove the
assumption that the sections are contiguous. Define a macro to shorten
references to offsets in ia64_sal_os_state.
This patch does not change the way that the code behaves. It just
makes it easier to update the code in future and to add fields to
ia64_sal_os_state when debugging the MCA/INIT handlers.
