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%
