not seem to impact performance and makes it a lot easier for people
embedding V8 to run their application under valgrind.

If we observe a negative performance impact, we will need to revise
this again.

overhead on the ARM platform.

Because virtual frames are always in memory, there is no work to be
done for control flow except in the case of breaking or continuing
when there is extra statement state on the stack.

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.
