* 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.

Reduce memory usage for storing LTO decl resolutions

With a LTO build of a large project (>11k subfiles incrementially linked)
storing the LTO resolutions took over 0.5GB memory:

lto/lto.c:1087 (lto_resolution_read)                      0: 0.0%  540398500           15903: 0.0%

The reason is that the declaration indexes are quite sparse, but every subfile
got a full continuous vector for them. Since there are so many of them the
many vectors add up.

This patch instead stores the resolutions initially in a compact (index, resolution)
format. This is only expanded into a sparse vector for fast lookup when
the subfile is actually read, but then immediately freed. This means only one
vector is allocated at a time.

This brings the overhead for this down to less than 3MB for the test case:

lto/lto.c:1087 (lto_resolution_read)                      0: 0.0%    2821456           42186: 0.0%
