9edc69c72f Add support for (some) assignment expressions to the CFG builder and
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.

98b93c739d Added support for expression statements to the CFG builder and
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.

5470f9b132 Add an ability to initiate GC through V8 API.
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.
