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,
