90772fa427 Change the SpilledScope scope and ...AndSpill functions on ARM so that
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.

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.

cffc051177 Avoid dictionary expansion during bootstrapping.
Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping.

Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added.  This gets rid of 10 dictionary expansions during bootstrapping.

There are now 3 dictionary expansions left during bootstrapping.
