they do nothing.  The frame is currently always spilled, so they were
not doing anything useful.

The call sites have been left alone to mark where spills will
eventually be needed if we begin doing register allocation on ARM.

fast-mode compiler.

1. We avoid generating a useless temporary for assignments with
nontrivial right-hand sides.  Instead of translating id = expr into:

...
tmp = <last expr instruction>
id = tmp

we generate directly

...
id = <last expr instruction>

by passing a data destination ('hint') down the AST.  The semantics is
to use the destination as a result location if a temp is needed.  It
may be ignored.  NULL indicates I don't care and you should generate a
temp.

2. We correctly handle assignments as subexpressions.  When building
the CFG for an expression we accumulate the assigned variables and we
emit a move to a fresh temporary if a value in a variable is in
jeopardy of being overwritten.

fast-mode compiler.

This will generate a compiler temporary for complex expressions and
then immediately throw it away, so a better approach (to be
implemented later) is to pass to the expression builder whether an
expression is in an effect or value context.

I'm planning to use it in DevTools heap profiler. It is a common scenario in debugging memory leaks to enforce GC, then perform an operation, then enforce GC again to check for non-collected (that is, leaked) objects. Using the existing GC extension isn't possible because it doesn't exposed in the normal operation mode of Chromium.

Optimization was only unsafe if new-space was in the low half of memory and an object could be
located in the top half at an addressed that only differ from a new-space address by the high
bit.

- Restructured the entire function because:
  During the simple style fix I discovered that this whole routine was
  hard to read due to a general lack of comments. While adding comments I
  realized that the function was also skipping entries if there were two
  consecutive entries in the maps file.
