gcc-4.6.0: Backport FSF 4.6 branch patches

This is set of bugfixes that has been done on
FSF gcc-4_2-branch since 4.6.0 was released

They will roll into 4.6.1 release once that
happens in coming approx 6 months time then
we can simply remove them thats the reason
so use a separate .inc file to define the
SRC_URI additions

+        * dwarf2out.c (based_loc_descr): If drap_reg is INVALID_REGNUM, use
+        as base_reg whatever register reg has been eliminated to, instead
+        of hardcoding STACK_POINTER_REGNUM.

+        * gcc.dg/guality/pr36977.c: New test.
