8243d96f08 Bug 501908: Avoid O(n^2) behavior when recycling large trees. r=igor 
It turns out that the careful effort RecycleTree and NewOrRecycledNode make
to disassemble the recycled tree lazily is wasted: every recycling call
ends up calling UnlinkFunctionBoxes and walking the entire parse node tree
to fix up funbox and method links. There's no locality; you might as well
queue up the parse nodes while you're at it. And the stack doesn't stay
shallow.

This patch replaces the (very clever) lazy recycling with eager recycling,
using a work stack chained through the nodes themselves to avoid creating
deep C++ stacks when recycling deep parse trees. We put off cleaning up the
method lists and funbox tree until just before function analysis, at which
point we do so in a single linear pass. Putting this off to the end avoids
quadratic behavior, as noted in the comments.

The patch localizes the process of adding nodes to the free list in a
single function, ensuring that we don't recycle used/defn nodes. It also
poisons newly freed nodes.

The patch also more clearly distinguishes between function nodes that have
been fully deleted, and function nodes that have been mutated (by
js_FoldConstants) into other kinds of nodes. See the comments before
Parser::cleanFunctionList.

I believe the patch also improves the care with which we handle nodes that
cannot be recycled immediately (those that appear in JSAtomLists, or are
referred to by JSFunctionBoxes). In some cases, those nodes may be picked
up and fiddled with later, so it is important that they not refer to nodes
around them that did get recycled.

780bba0f9f Bug 501908: Pass a JSTreeContext to analyzeFunctions, not bits and pieces. r=igor 
Proper function recycling may mean eliminating the tree context's entire
function list; it's misleading to pass in the function list, rather than
side-effecting the tc in place.

Let analyzeFunctions take care of testing whether we have any functions to
analyze, instead of making each caller do it. In the next patch in the
series, we won't know whether the function list is really clear or not in
the callers anyway.

Avoid passing tcflags around by non-const reference; SpiderMonkey style is
to use pointers for parameters the callee may mutate, to make call sites
more evidently potential mutations.
