Allow reservation of additional input capacity when creating nodes to prevent switching to deque representation when adding well-known additional inputs.

Also ensure that only a single temporary buffer is used to create temporary input arrays before allocating nodes.

This avoids using the Sparse methods on objects with non-enumerable elements,
which can cause the 'enumerable: false' bit to get lost in the operation.

They were not, so we were creating several instances of them, one for each time
they occurred in the source code.

It's not known to have caused efficiency problems though, so this is a sanity
fix more than an efficiency fix.

Note that numbers are still not unique.

Private symbols we create in the heap don't have names, but we can
resolve them to a constant string.

This gives handy debugger output like:

(gdb) job 0x2020c67d
0x2020c67d: [Symbol]
 - hash: 547385396
 - name: 0x20208091 <undefined> (uninitialized_symbol)
 - private: 1
 - own: 1
$7 = void
(gdb)

or with ShortPrint() in an array:

...
  [5]: 0x2020c67d <Symbol: 547385396 (uninitialized_symbol)>
...

Each time a transition is added to a hidden class, the whole
transitions array must be copied, which causes poor performance
in some circumstances.  This change limits the maximum size of
the transition array, avoiding this behavior in the pathological
case.  For example, this improves the performance of the EtchMark
benchmark by nearly 60%.
