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.

f66ea38c0b Allocate arguments object on-demand instead of at function entry.
This allows Function.prototype.apply to not allocate the objects 
and copy the arguments directly from the stack.

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.

edf51c0fa9 Optimize the scope creation code by lazily allocating the hash maps
for dynamic variables (only do it for the scopes that need them).

0c7af39737 Speed up access to global variables from eval scopes. Traverse the
surrounding context to figure out if the variable could be global.  If
the variable could be global we check context extension objects at
runtime and use a global LoadIC if no variables have been introduced
by eval.

Fix crash bug when loading function arguments from inside eval.  The 
shadowed variable in the DYNAMIC_LOCAL case does not rewrite to a slot in 
that case.

b4b5e3ca95 Not sure what happened, but my revert did not get everything out. Fixing the problem instead. The issue was using tmp instead of context in two places.

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.

5fa3bd8440 Remove unused code. This code used to be used to "decide" if a call
to eval is aliased.  Now that we correctly track eval aliasing, we do
not need this code.
