Daily bump.

From-SVN: r191169

* testsuite-management/x86_64-unknown-linux-gnu.xfail: Update.

From-SVN: r191166

Remove unnecessary VEC function overloads.

Several VEC member functions that accept an element 'T' used to have
two overloads: one taking 'T', the second taking 'T *'.

This used to be needed because of the interface dichotomy between
vectors of objects and vectors of pointers.  In the past, vectors of
pointers would use pass-by-value semantics, but vectors of objects
would use pass-by-reference semantics.  This is no longer necessary,
but the distinction had remained.

The main side-effect of this change is some code reduction in code
that manipulates vectors of objects.  For instance,

-  struct iterator_use *iuse;
-
-  iuse = VEC_safe_push (iterator_use, heap, iterator_uses, NULL);
-  iuse->iterator = iterator;
-  iuse->ptr = ptr;
+  struct iterator_use iuse = {iterator, ptr};
+  VEC_safe_push (iterator_use, heap, iterator_uses, iuse);

Compile time performance was not affected.

Tested on x86_64 and ppc64.

Also built all-gcc on all targets using VEC routines: arm, bfin, c6x,
epiphany, ia64, mips, sh, spu, and vms.
