Implementation of the harmony block scoped let bindings as proposed here:
http://wiki.ecmascript.org/doku.php?id=harmony:block_scoped_bindings

Changes to the syntax are explained there. They are active under the
harmony_block_scoping_ flag in the parser.

95c76ed464 Remove some dead code. 
- virtual-frame*
- register-allocator*
- jump-target*
- most of codegen*
- AstOptimizer and fields on AST

There is a lot of additional cleanup that we should do but this gets
rid of a lot.

9c503a8330 Fix some inconsistent formatting. 
I noticed we sometimes had extra spaces before and after the "const"
keyword.  Probably the result of a search and replace gone wrong.

This is a whitespace only change.

830185b175 Clean up some messiness in Scopes. 
For some reason, the scope's arguments and arguments shadow were
variable proxies, which resulted in all references to the arguments
shadow being shared in the AST.  This makes it hard to put per-node
state on the AST nodes.

I took the opportunity to remove Variable::AsVariable which has
confused people in the past, and to rename Variable::slot to the more
accurate Variable::AsSlot.

43fd945eee Loop peeling for inner loops. 
This change adds the option to peel off the first iteration of inner loops.

Loop peeling is off by default and can enabled by a flag. It also requires building a flow graph.

As part of this I added the possibility to clone AST nodes.

bce8d2ebae Remove unneeded variable usage analysis. 
A variable usage analysis pass was run on toplevel and lazily-compiled
code but never used.  Remove this pass and the data structures it
builds.

The representation of variable usage for Variables has been changed
from a struct containing a (weighted) count of reads and writes to a
simple flag.  VariableProxies are always used, as before.  The unused
"object uses" is removed.

8e6bf58174 Allow variable proxies for the same global variable to share the same 
variable object.

Add a map from names to variables for global scopes just like
non-global scopes.  Variables are added to the map by the parser when
it encounters a declaration in a global scope or else at scope
resolution time by a failed variable lookup from the global scope or
an inner one and with no intervening with statements or possible calls
to eval.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide. 
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

a09832ab76 Optimize loads from variables that might be shadowed by variables 
introduced by eval.

In the cases where calls to eval have not introduced any variables, we
do not need to perform a runtime call.  Instead, we verify that the
context extension objects have not been created and perform a direct
load.

Not implemented for ARM yet and the scope resolution code could use
some better abstractions.  I'd like to do that in a separate
changelist.
