When strings can change from an ASCII representation to a

UC16 representation we need to be careful about flat strings.
Flat strings can be sliced or cons strings that have a flat
string under them, so when we ask a flat cons or a slice whether
it is ASCII or not we should ask the underlying string about
its representation. This should fix

There are lot of room for code refactoring in stead of using #ifdef all over the place. I will leave this to v8 folks.

If an external string enters the symbol table, make sure to set the
...
resource to NULL when removing it from the symbol table. This makes
sure that the debugger can recognize the external string as being
"deleted". Now, whenever an external resource is deleted, the
resource pointer is set to NULL.
This is really a workaround of a debugger problem. We need to make
sure that the debugger only finds scripts in the heap that are
actually live.

Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

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.

Changed all log messages to be handled through the LogMessageBuilder instead of through fprintf directly to the log file.
...
Added a flag for the runtime %Log call and fixed its arguments checking. Use of %Log is only for debugging.
