b092d55890 Enable --trace when --multipass is on. Bugfix in bailout condition.
All V8 and (ia32) mozilla tests pass with --multipass on, failures now
count as regressions.

3a472fada8 Basic infrastructure for fast two-pass compilation. A CFG is
generated in one-pass from the source AST, code is generated from the
CFG.  Enabled by the flag --multipass and disabled by default.

Rudimentary and currently only supports literal expressions and return
statements.  There are some other known limitations (e.g., missing
support for tracing).

a48fd5916e Change the overly-general class named Node to the more specific
AstNode in case we ever want to have some other kind of node.

Split the NODE_LIST macro-generating macro so that we can iterate
concrete subclasses of Statement and concrete subclasses of Expression
separately.

1ca19c383d Fix ARM compiler crash in short-circuited boolean expressions.
We did not handle the case where the left-hand-side expression was
fully compiled to control flow.  There were also some assertions for
unary and binary expressions that crashed debug builds when the
expression was fully compiled to control flow.

Regression test added.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.
