PATCH: Apply more of Kenner's patch to 3.4 branch

[Mark Mitchell]

This backport to 3.4 branch was incomplete:

2005-05-09  Grigory Tolstolytkin  <gtolstolytkin@ru.mvista.com>

         Backport from mainline
         2004-02-12  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>
         * emit-rtl.c (set_mem_attributes_minus_bitpos): Don't kill
         previous MEM_VOLATILE in REF.

I've now also applied:

2005-05-10  H.J. Lu  <hongjiu.lu@intel.com>

         Backport from mainline
         2004-02-12  Richard Kenner  <kenner@vlsi1.ultra.nyu.edu>
         * function.c (fixup_var_refs): Save volatile_ok and set to 1.
         * expr.c (emit_block_move_via_movstr): Save and restore
         volatile_ok.

to fix the Ada bootstrap issue reported by Andreas et. al.

I'll take another stab at an RC1 build, now that the Ada problems should 
be fixed.
