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.

For parallel LTO builds setting -fmem-report does not work very well
because all the LTRANS phases dump it in parallel and typically interleave
it to unreadability.
Since usually the memory bottleneck is WPA add a flag to only dump
the memory report for that.

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
orders.
