This fixes PR gcov-profile/54487 where the gcda files were not locked
by the profile-use read, enabling writes by other instrumented compiles
to change the profile in the middle of the profile use read. The GCOV_LOCKED
macro was not set because it was guarded by HOST_HAS_F_SETLKW, which was
never set. The fix is to add a compile test in the configure to set it.

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.

This fixes part of the issue described in PR gcov-profile/54487 where
there were warnings about mismatches due to slight differences in the
merged histograms in different object files. This can happen due to
the truncating integer division in the merge routine, which could result
in slightly different histograms when summaries are merged in different

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%
